Ian Rapoport of the NFL Network reports that the 49ers have reached an agreement with CB Tramine Brock on a four-year deal worth $16 million that includes $7 million guarantee.
Brock, 25, took over as the team’s nickel back in Week 5 after they sent Nnamdi Asomugha, who was later released, to the bench. He will make his first start on Monday now that Tarell Brown is out with an injury.
Pro Football Focus has Brock rated as the No. 18 qualifying cornerback in the league this season. Brock has 18 total tackles this season to go along with four interceptions (one for a touchdown), and nine pass defenses.
Brock was in the final year of his current deal, so this move will keep him under contract through the 2017 season. This is almost identical to the contract the Patriots handed out to CB Kyle Arrington back in March. Arrington, 26 at the time, received a four-year deal worth $16 million, but his contract included $8 million guaranteed.
