Nearly one year after he tore his left ACL as a member of the 49ers, Kyle Williams suffered the same injury with his new team, the Chiefs. Williams revealed the injury on Twitter. "Saddened to say I will be missing the remainder of the season due to another tear of my ACL," he wrote Friday morning.
The Chiefs later announced they had placed Williams on injured reserve and signed another ex-49ers receiver, Chad Hall, to take his place.
Williams tore his ACL on Nov. 25 in New Orleans last season, the same day that running back Kendall Hunter suffered a torn Achilles' tendon. Williams made a quick recovery and began the season as the 49ers' kick and punt returner as well as the No. 2 wide receiver.
However, he did not make an impact in any of those areas. With Mario Manningham returning from his own ACL injury, the 49ers cut Williams last week, and he was later signed by the Chiefs. He played four snaps in his debut against the Broncos on Sunday. It's not known whether his injury occurred in that game or at practice.
Another 49ers receiver, A.J. Jenkins, played two snaps against Denver.
