Spencer (ankle) returned to practice on Monday, Jim Wyatt of The Tennessean reports.

Spencer had missed two weeks due to an ankle injury suffered on Aug. 9 against Green Bay. He'll resume his backup role behind starting center Brian Schwenke.

Spencer picked up an ankle injury in last Saturday's preseason opener against Green Bay, Jim Wyatt of the Tennessean reports.

Spencer was seen wearing a walking boot at practice on Wednesday, but it remains unclear how much time he'll miss. As a result of Spencer's injury, center Steve Vallos was signed on Wednesday.

Titans re-signed G/C Chris Spencer.

It was initially reported that Spencer, 32, was viewed as merely a fallback option for the Titans, who had three interior linemen in for visits Wednesday. Instead, GM Ruston Webster goes with a guy he knows. Spencer is purely a backup.

Free agent G/C Chris Spencer is only considered a fallback plan for the Titans.

Free agent Gs Uche Nwaneri and Garrett Reynolds and G/C Eric Olsen visited the Titans on Wednesday. Tennessee is set with its starting interior unit but its in the market for capable backups. Spencer is 32 years old.

Titans agreed to terms with G/C Chris Spencer, formerly of the Bears, on a one-year contract.

Spencer, 31, started five games -- two at right guard and three at left guard -- for the Bears last season. Tennessee continues its splurge on the free-agent market, and Spencer could compete with recent addition Rob Turner for the right guard job. Ideally, the two veterans would be backups.

Free agent G/C Chris Spencer is visiting the Titans on Tuesday.

Spencer spent a good chunk of 2012 at left guard for the Bears, but missed six games with knee issues. He didn't acquit himself well when he was on the field. The Titans are remaking their interior line, but a best-case scenario for Spencer would have him competing with Rob Turner at right guard. The Titans may not be done making moves at guard.

Bears LG Chris Spencer (knee) is expected to miss 1-2 weeks.

The Bears with be without both starting guards against the Seahawks this week, forcing OT Gabe Carimi to move inside along with backup Edwin Williams. Former Cowboys C Andre Gurode has been signed for depth.

Bears LG Chris Spencer's Monday MRI revealed some torn cartilage in his left knee, but it's "not believed to be serious."

Spencer was just put back in the starting lineup for Chilo Rachal in Week 12, but he was forced to leave midway through the contest with the injury. Edwin Williams replaced Spencer at left guard. Chicago has some serious offensive line issues with RG Lance Louis tearing his ACL on Sunday, too. Spencer's timetable for return is unclear.

The Bears have benched LG Chris Spencer in favor of Chilo Rachal.

Left tackle J'Marcus Webb took the heat from Jay Cutler last Thursday night, but Spencer ends up taking the fall. Cutler was sacked seven times and was harassed into four interceptions. Rachal showed significant upside with the Niners in 2010 before losing his job to Adam Snyder in 2011.

The Bears have moved Chris Spencer to left guard, where he is working with the first-team offense at OTAs.

Primarily a center throughout his career, Spencer struggled mightily as a pass blocker last season along with the rest of Chicago's offensive line. He focused on right guard last year, but is being counted on to take over for Chris Williams at left guard. Williams is now pushing J'Marcus Webb at left tackle.

Bears C/G Chris Spencer will play through his broken hand.

Spencer fractured his hand in the first quarter of Sunday's win over the Panthers and returned after halftime with a cast on it. Where he'll line up against the Lions Monday night is unclear. The Bears are scuffling to replace Gabe Carimi (knee) at right tackle.

Bears RG Chris Spencer left Sunday's game against the Panthers with a hand injury.

Spencer is questionable to return. It was his first start of the year, in place of an ineffective Lance Louis. Now Louis is in the game. Ah, the irony.

Bears agreed to terms with C Chris Spencer on a two-year contract.

Olin Kretuz's 13-year Bears career appears to over as the sides stood $500,000 apart in contract talks. Spencer has started 70 games in Seattle the past five years, but the Seahawks were all too willing to let him walk this offseason. He graded out as a bottom-tier run blocker -- along with Kreutz -- in Pro Football Focus' ratings.

ESPN's John Clayton confirmed on ESPN's Inside the Huddle Thursday that free agent C Chris Spencer is unlikely to return to Seattle.

Seahawks brass envisions former second-round pick Max Unger as their new starting center. Spencer, 29, was the club's first-round pick in 2005. He turned in just the second 16-start season of his injury-plagued career last year, but struggled across the board and is destined for a backup job in free agency.

Seahawks C Chris Spencer left late in Sunday's loss to the Chiefs with a leg injury and did not return.

This won't do anything to help Spencer's injury prone label. He'll undergo more testing Monday.

Seahawks re-signed restricted free agent C Chris Spencer to a one-year contract.

Spencer has returned to center in this week's minicamp after being moved to right guard last season. Early indications have him staying there with Max Unger moving over to guard.

Chris Spencer has been back at center in this week's practices after finishing last season at right guard.

"He's a natural center," said coordinator Jeremy Bates. "He's quick off the ball. He has great hands. He's a leader of that line. He's nasty." Expect last year's second-rounder Max Unger to move back to right guard in Seattle's zone-blocking scheme.
