SANTA CLARA, California — The San Francisco 49ers have placed center Daniel Kilgore on the reserve/physically unable to perform list as he works back from a second procedure on his left fibula that he fractured last October.
Kilgore had another operation in June and coach Jim Tomsula isn't sure when he will be ready to return.
Among the 10 players cut Monday was former British discus thrower Lawrence Okoye.
San Francisco waived placekicker Corey Acosta, linebacker Steve Beauharnais, cornerback Mylan Hicks, tackle Sean Hooey, wide receivers Mario Hull, Chuck Jacobs and Nigel King, linebacker Shawn Lemon and fullback Trey Millard.
The 49ers have 75 players on the roster, which must be trimmed to 53 by Saturday.
