KANSAS CITY, Mo. (AP) -- The Kansas City Chiefs had hoped wide receiver Kyle Williams would provide some speed and a spark to an offense that was desperately in need of both.
Williams never got the chance to show it.
Little more than a week after he was claimed off waivers from San Francisco, and after just one game spent on special teams, Williams was placed on injured reserve Friday after partially tearing the ACL in his surgically repaired left knee.
Chiefs coach Andy Reid said that the injury occurred during Thursday's closed practice.
''Saddened to say that I will be missing the remainder of the season due to another tear of my ACL,'' Williams said on Twitter. ''This, just like everything else I've been through, will serve as a minor hurdle and obstacle that I will push through and will be back.''
The Chiefs had released wide receiver Chad Hall when they acquired Williams, and brought Hall back on Friday. It's unlikely he'll be up to speed in time for Sunday's game against San Diego.
''Williams' situation yesterday was that he practiced the whole practice, and tweaked his knee to where he tweaked it and never missed a play,'' Reid said. ''He had that surgically repaired and he partially tore his ACL, the same ACL that he has worked his tail off to get back.''
Williams tore the ligament during the 49ers' game against New Orleans a year ago this week. He spent the offseason rehabbing and played in nine games for San Francisco before he was waived.
The Chiefs quickly snapped him up to provide another weapon for their passing attack, which has struggled to get on track. Kansas City is averaging fewer than 200 yards passing per game, 26th out of the 32 teams in the NFL, and quarterback Alex Smith has just 11 touchdown passes.
Offensive coordinator Doug Pederson said before Thursday's practice that Williams had spent his first week with the team picking up the offense and was finally ready to contribute.
''I want to give him a few reps, a few plays this week and get him into the ballgame, see how he handles the information and the volume of the information, especially during the game,'' Pederson said. ''So, we're excited to see him in action.''
Hall has played in 22 games in just over two NFL seasons with the Chiefs and Eagles. He was claimed off waivers on Sept. 1 from the 49ers and played in seven games with Kansas City, making one catch for 9 yards. Hall also returns kicks.
In other injury news, defensive tackle Mike DeVito was ruled out for Sunday's game against the Chargers after hurting his knee in last week's loss to Denver. The Chiefs signed veteran Kyle Love this week and it's possible he could be active against San Diego.
Right tackle Eric Fisher, the No. 1 overall pick in the draft, is doubtful with a shoulder injury. His running mate, right guard Jon Asamoah, is questionable with his own shoulder injury.
Defensive end Tyson Jackson is also questionable with a strained abdominal muscle, and Reid said that Love or rookie Mike Catapano could fill in for him.
''Both of them are ready to play and both of them took reps,'' Reid said.
