Williams was added to the Cardinals' practice squad Wednesday, the team's official site reports.

Promoted to the Cardinals' active roster in advance of Week 2 to serve as running back depth with Andre Ellington (knee) out of commission, Williams garnered only eight of 59 offensive snaps, which he translated into one carry for three yards. If Ellington sits out again Sunday versus the 49ers, Williams could again be bumped up to the 53-man roster.

The Cardinals have waived Williams.

The move creates a roster spot for the reinstatement of tackle Bobby Massie, with the Cards having bolstered their backfield depth by adding Mike Gillislee to their practice squad.

The Cardinals have promoted Williams from their practice squad to the team's active roster in advance of Week 2.

With Andre Ellington injured, Williams will bolster the Cards' backfield depth, though as it stands now he figures to slot in behind both Chris Johnson and David Johnson in the team's running back pecking order, with Stepfan Taylor also in the mix on that front.

The Cardinals added Williams to the practice squad Monday, the team's official site reports.

Williams' release Saturday wasn't a surprise due to the state of the Cardinals' running-back corps, which is populated by Andre Ellington, Chris Johnson, and rookie David Johnson. Because Williams' skill set lines up with the trio, he would be the logical candidate to fill in in case of injury. In four preseason games, Williams turned 23 rushes into 77 yards and one touchdown.

Williams was released by the Cardinals on Saturday, Josina Anderson of ESPN reports.

After Chris Johnson fared well in Thursday's preseason finale -- 11 carries for 45 yards -- the writing was on the wall for Williams due to the relative depth at running back in Arizona. Williams may not have trouble finding a landing spot, though, after taking 23 carries for 77 yards and one touchdown through four exhibitions.

Williams had five carries for nine yards in Saturday's preseason game against the Chargers.

Williams' roster chances took a big hit when Chris Johnson (hamstring) was signed, but there's now some chance that the veteran won't be ready by Week 1. Williams did himself no favors Saturday night, and he'll likely just be the No. 3 or 4 running back if he makes the final roster.

Williams received 17 snaps in Saturday's preseason defeat to the Chiefs, taking seven carries for 20 yards, Mike Jurecki of FOX Sports 910 Phoenix reports.

After Andre Ellington handled the opening series, Williams was given the next opportunity to head the backfield, doing so for three fruitless drives. Williams' line would have received a boost if his long run of 14 yards wasn't wiped away by an offensive holding call, but five of his seven rushes failed to surpass four yards. Nevertheless, David Johnson's (hamstring) continued absence has seemingly afforded Williams the valued role of Ellington's primary backup to this point of exhibition season.

Williams (hamstring) took on more work than normal Sunday due to the hamstring injuries afflicting Andre Ellington and David Johnson, Kent Somers of the Arizona Republic reports.

Williams himself missed some time in June's minicamp due to a minor hamstring concern but is back to full health at the outset of training camp. After Ellington was lost for the season, Williams helped sustain a modest rushing game and even recorded the sole 100-yard performance for a Cardinals running back in Week 14 against Kansas City. While he resides behind both Ellington and Johnson on the depth chart, the fact that coach Bruce Arians turned to Williams bodes well for his ability to land a spot on the final 53-man roster.

Williams sat out the Cardinals' minicamp due to a minor hamstring injury, the Arizona Republic reports.

Williams in fact sat out the final week of OTAs as well, which combined with Stepfan Taylor's absence to afford 2015 third-round pick David Johnson reps with the first- and second-team offenses this week. In the meantime, head coach Bruce Arians was pleased with the progress made by his team in the offseason program and subsequently nixed the final practice of minicamp from the schedule. As a result, Williams likely will enter training camp as the third option, at best, on the depth chart at running back.

Williams is tending to a hamstring injury, which is expected to hold him out of the final week of Cardinals OTAs, Kyle Odegard of the team's official site reports.

Williams' absence from practice appears to be a precautionary measure, but the true extent of the injury will be clear if he misses any of next week's mandatory minicamp. Currently, he's among a cadre of runnings backs vying for the primary backup role to Andre Ellington -- also, Stepfan Taylor, Marion Grice, and 2015 third-round pick David Johnson -- with any missed time a hindrance in that endeavor. No matter, Williams showed himself well in a five-game sample with the Cardinals last season, racking up 269 on 63 carries, which was good for 4.27 YPC.

Williams ran 10 times for 23 yards and caught three passes for zero yards in Saturday's playoff loss to the Panthers.

Williams received more touches than the rest of the Cardinals' running backs combined, but he was limited by the Cardinals' lackluster offense, and sat watching as fellow running back Marion Grice punched in a touchdown from the one-yard line. Williams is unlikely to start ahead of a healthy Andre Ellington next season, but he could contend for the backup job after averaging 4.6 yards per carry over the final four weeks of the regular season.

Williams turned 17 carries into 67 yards during Sunday's defeat in San Francisco.

After coach Bruce Arians ditched the running game last Sunday against the Seahawks -- 45 passes and 15 runs -- he recommitted to his backs in the regular season finale, aiding Williams' bounce-back effort. Since Williams entered the Cardinals' RB fray in Week 14, he's earned 53 carries and six targets, versus Stepfan Taylor's 38 and five, respectively. Arians is likely to stick with a similar breakdown of work in next Saturday's wild-card contest in Carolina, who surrendered 4.5 YPC to running backs during the season's final five contests.

Williams (knee) had two carries for four yards in Sunday's 35-6 loss to the Seahawks.

One week after splitting the workload with Stepfan Taylor, Williams was not targeted in the passing game, while Taylor got the starting nod, 11 carries and two receptions. Marion Grice had one carry and four targets (one catch), with Robert Hughes also getting one carry. After Taylor managed just 19 yards on those 11 carries, the Arizona backfield situation will likely be hard to predict for a tough Week 17 matchup with the 49ers. As the final score indicates, the Cardinals were completely incompetent on offense Sunday night.

Williams (knee) is listed as active Sunday against the Seahawks, the Cardinals' official site reports.

Williams has emerged suddenly the past two weeks, racking up 175 yards rushing on 34 carries. Because the Cardinals are turning to Ryan Lindley at quarterback, the Cardinals' best chance for victory is controlling the clock, meaning a combination of Williams and Stepfan Taylor will be required to take down the defending champions.

Williams (knee) is probable for Sunday's game against Seattle.

Williams has been awfully impressive and his knee isn't a concern, but the matchup is a very tough one. The Seahawks defense is usually dominant on its own merits, and this game might end up being tee-ball to them since Ryan Lindley is starting at quarterback. Williams will see stacked fronts, so he'll have to be pretty brilliant to find the open field.

Williams (knee) was limited in practice Wednesday, FOX Sports 910 Phoenix reports.

Williams is so far averaging more than five yards per carry -- 5.1, to be exact -- as he's helped provide a semblance of balance to the Cardinals' offense since Andre Ellington (hernia) was lost for the season. On Sunday, Williams' services will again be required against the Seahawks in a game that could ultimately determine the NFC West champion.

Williams had 15 carries for 75 yards, adding two receptions for 11 yards on five target, in Sunday's 12-6 win over the Rams.

Stepfan Taylor started and had 14 carries for 61 yards, but he did not see any targets. While both running backs fared surprisingly well against a tough St. Louis front seven, Williams nearly lost a fumble in the final five minutes, with the Cardinals protecting a six-point lead. Taylor got the next three carries, but Williams came back for a two-yard carry on Arizona's final offensive play. Meanwhile, Marion Grice and Robert Hughes each played a few snaps, but neither recorded a target or carry. In all likelihood, Taylor and Williams will split the workload in a difficult Week 16 matchup with the Seahawks.

Coach Bruce Arians indicated Monday that Stepfan Taylor is still the Cardinals' starter at running back, though the team figures to employ a committee approach in which Williams will get his chances to remain a factor, Darren Urban of the team's official site reports.

Per Kent Somers of the Arizona Republic, Arians is inclined to ride the hot hand, which Williams was this past Sunday, en route to recording 19 carries for 100 yards. Meanwhile, Taylor carried six times for 19 yards and Marion Grice ran three times for six yards. In any case, regardless of who the team's starter is in name, the spark that Williams provided the team's attack in Week 14 figures to earn him a chance Thursday (against the Rams) to build off his surprising effort this past Sunday. Williams thus remains worthy of a speculative pickup, in particular by those who roster (or rostered) Andre Ellington, who landed on IR on Monday.

Williams carried 19 times for 100 yards in Sunday's win over the Chiefs.

With fellow RB Andre Ellington headed to IR, per Darren Urban of azcardinals.com, Williams looks poised to head the the Cardinals' rushing attack down the stretch, an assignment that makes him a must-add this week. Urban relays via coach Bruce Arians that Williams' surprisingly big role Sunday was the result of the running back being the only player on the practice field to "make players go wow" over the last three weeks.

The Cardinals promoted Williams from their practice squad Friday, Kent Somers of AZCentral.com reports.

Williams will be up to replace Michael Bush on the active roster, though it's no lock that he'll even be active against the Chiefs in Week 14. Stepfan Taylor and Marion Grice are expected to handle the bulk of the carries with Andre Ellington out with a hip injury.
