Richardson has decided to retire from the NBA, Marc Spears of Yahoo! Sports reports.

Richardson inked a non-guaranteed deal with the Hawks last month due to the team's status as a contender, but after enduring some discomfort in his right knee over the past 4-to-5 days, an MRI revealed bone spurs in the knee. Considering he sat out the 2013-14 season due to injury and logged 52 games combined in the past three campaigns, yet another ailment was seemingly setting up the 34-year-old guard for another injury-plagued season, if he made the Hawks' roster at all. Known for his dunking prowess, Richardson will end his career No. 16 on the career three-pointers made list with 1,608, while providing 17.1 points (on 44 percent shooting), 5.0 rebounds, 2.7 assists, 1.9 threes, and 1.2 steals in 34 minutes per contest.

Richardson will sign a non-guaranteed contract with the Hawks on Monday, Yahoo! Sports reports.

Richardson was sidelined for more than two years due to a knee injury, but upon his return on Feb. 20, he played in 19 of the Sixers' final 29 games. Earning the starting nod in 15 of them, he averaged 9.1 points (on 35 percent shooting), 3.5 rebounds, 2.0 assists, 1.6 three-pointers, and 0.7 steals in 22 minutes. He'll aim to factor into a wing rotation that could be without the services of Thabo Sefolosha (leg) to start the regular season.

Richardson averaged 9.1 points (35% FG, 32% 3Pt, 77% FT), 1.6 three-pointers, 2.0 assists, 3.5 rebounds, and 0.7 steals in 22 minutes per game for 19 regular season games in 2014-15. He is an unrestricted free agent this summer.

After not playing basketball for two years due to a left knee injury, Richardson rejoined the 76ers in late February with a limited role. Heading into 2015-16, he'll need to stay healthy to earn a feature role on a team. Fantasy owners should keep an eye on where he ends up in free agency to better gauge his future production.

Richardson (knee) will not play against the Bucks on Monday, Keith Pompey of the Philly Inquirer reports.

The veteran is experiencing soreness in his surgically repaired knee, so he'll be held out for the second time in five games. Richardson scored 17 and 19 points, respectively, in his last two games.

Richardson (rest) posted seven points (3-11 FG, 1-6 3Pt) to go with three rebounds and one assist in 23 minutes of action Sunday against the Knicks.

Richardson has been sitting out occasionally due to rest, so it's not hard to imagine him missing a few more games down the stretch. Still, he's been fairly one-dimensional in fantasy this season, and his poor FG percentage puts him out of contention for ownership in all but 18-man leagues or deeper.

Richardson (rest) will play Sunday against the Knicks, Keith Pompey of the Philadelphia Inquirer reports.

Richardson skipped Saturday's contest as the first of back-to-back games for the 76ers. It appears missing the tilt allowed him to be available for Sunday's game, but Robert Covington will start at shooting guard again, so his minutes will likely be limited.

Richardson will be rested for Saturday's game against the Hornets, Keith Pompey of the Philly Inquirer reports.

The veteran has rested periodically this season since returning from a major knee injury in February. He played only six minutes against Washington on Wednesday and is not much of a daily option, due in large part to his inconsistent role.

Richardson (knee) logged six minutes Wednesday against the Wizards and posted just one rebound.

Richardson has been dealing with ailments over the past seasons, and this last month has been no exception. His fantasy value is limited, even on a weak Sixers squad.

Updating a previous note, Richardson (knee) has now been cleared to play Wednesday against the Wizards, Keith Pompey of the Philly Inquirer reports.

Richardson's knee has been sore of the last few days, and he was initially ruled out with Jerami Grant penciled in as the starter. The team hasn't stated whether Richardson will enter the starting five, but he'll be available in some capacity for coach Brett Brown.

Richardson (knee) will remain out Wednesday against the Wizards, Keith Pompey of the Philadelphia Inquirer reports.

Richardson returned from major knee surgery earlier this season, and he's been battling routine soreness over the past week. The team will hold him out again Wednesday, meaning Robert Covington will likely remain in the starting lineup. Covington is averaging 15.5 points, 4.5 rebounds and 2.5 assists while making eight threes over his last two games.

Richardson (knee) is slated to miss a few games, Keith Pompey of the Philly Inquirer reports.

Richardson missed Sunday's game, and at this point it appears he's dealing with routine soreness following major knee surgery. The Sixers haven't handed down a timetable, but the veteran is likely to miss at least a couple of games, beginning Monday against the Lakers. Robert Covington will make another start in Richardson's place.

Richardson will not start Friday against the Clippers, according to Calkins Media.

Richardson started and played 25 minutes in Philadelphia's last game Wednesday, but he will be replaced in the lineup for Friday's game by Robert Covington.

Richardson will return to the starting lineup Wednesday after resting Sunday, Max Rappoport of Sixers.com reports.

Richardson was given the night off Sunday after taking part in each of the team's five previous games. He'll return to the starting five at shooting guard, pushing Robert Covington back to the bench.

Richardson (rest) will not play in Tuesday's game against the Kings, Max Rappaport of Sixers.com reports.

Richardson isn't playing in both games of back-to-backs this season, and the Sixers have elected to save him for Wednesday's matchup with the Nuggets. Robert Covington will start in Richardson's place Tuesday night.

Richardson (rest) is starting Saturday against the Nets, the Bucks County Courier Times reports.

Richardson followed protocol and sat out the front end of a back-to-back set Friday against the Kings, meaning his return was expected Saturday. In eight nods this season, he's averaging 10.6 points (on 35 percent shooting), four rebounds, 2.1 assists, 1.9 three-pointers, and one steal in 25 minutes.

Richardson will sit out Friday's game, Sixers.com's Max Rappaport reports.

He will continue to rest one game of each back-to-back, but should be back in the lineup Saturday. Richardson filled it up for 29 points last week, so there is some upside here, but that is by far his best game of late.

Richardson (knee) logged 19 minutes Wednesday against the Bulls and contributed four points (2-9 FG, 0-6 3Pt), two rebounds, two assists, and two steals.

Richardson has had his ups and downs over the past few weeks, but his inconsistency has been frustrating. He's averaging 10.6 points, 4.0 rebounds, 1.0 steals, and 1.9 three-pointers made in eight games this season, just enough to make him worth a spot in 16-man leagues. Still, he'll rest the occasional game, so owners shouldn't rush to pick him up unless they're extremely desperate for threes.

Richardson (knee) will not play Saturday against the Hawks.

Richardson played 27 minutes in Friday's loss to Utah, so he'll be held out, as expected, on the second night of the back-to-back set. Robert Covington enters the starting lineup in his place.

Richardson had 29 points (8-19 FG, 4-9 3Pt, 9-9 FT), six rebounds, three assists and one steal in 36 minutes in Wednesday's overtime loss against the Thunder.

He sat out Monday's loss to the Raptors, but showed up ready to play against Oklahoma City. He's played in six games this season and this was by far his best. He can fill it up, and if he's healthy he will get every chance to do just that for the 76ers.
