The team announced a three-year extension with center Daniel Kilgore on Thursday. Kilgore was a fifth-round pick in 2011 and has played in 33 games for the Niners over the past three years.
There are no details on the terms of the deal. Kilgore has one year left on his rookie contract and would join Raiders special teamer Daniel Kilgore and Eagles center Jason Kelce as members of his draft class to get extensions.
