Quarterback Alex Smith and wide receiver A.J. Jenkins aren’t the only former 49ers on the Chiefs offense anymore. Wide receiver Kyle Williams is the latest to make the move from San Francisco to Kansas City. Williams was waived by the 49ers on Tuesday and claimed by the Chiefs on Wednesday. Williams broke the news himself via Twitter. Williams got a lot of time on the 49ers offense this season, but didn’t do all that much with it. He had 12 catches for 113 yards and wasn’t doing much better as either a punt or kickoff returner.
