The San Francisco 49ers and CB Tramaine Brock have agreed to a 4 year contract, worth $16 million, according to Ian Rapoport of NFL.com.
Brock is scheduled to make his first official start of the season when the 49ers take on the Redskins on Monday night, after right CB Tarell Brown injured his rib in the team's loss to the Saints on Sunday. He had previously served as the team's nickel back after Nmandi Asomugha was sidelined earlier this season.
Brock is in his 4th year in the league, all of which have been with San Francisco.
