CLEVELAND -- The Browns signed quarterback Seneca Wallace to a three-year deal Thursday night worth $9 million plus incentives, a league source said.

Wallace, a ninth-year pro, is well-versed in the West Coast offense being installed by new coach Pat Shurmur.

Wallace said last week he wanted a chance to start somewhere, but he'll begin as a backup here to Colt McCoy. The Browns have also said they wouldn't rule out having Jake Delhomme back, but he's set to make $5.4 million in 2011.

Wallace went 1-3 in his four starts last season, but was coming on strong in his last couple of starts before suffering a high ankle sprain agains the Falcons on Oct. 10.

In that game, Wallace completed 11-of-15 attempts fro a 139 yards and a TD for a 124.0 rating. After recovering from the sprain, he played sparingly in the Wildcat. Shurmur said last week that he liked Wallace a lot, and not just to run the Wildcat, but as a boma fide West Coast quarterback.
