Raiders to sign backup quarterback Seneca Wallace

Seneca Wallace may have lost out to Brady Quinn for the Seahawks backup quarterback job on Tuesday, but he apparently nailed his second audition of the week and will sign with the Raiders, according to CBS Sports' Jason La Canfora.

Wallace reportedly competed against Tyler Thigpen -- for the second time this week -- and possibly others in an audition for the Raiders.

Wallace could possibly compete with Terrelle Pryor for  the No. 2 job or fill the roster as a No. 3 quarterback behind starter Matt Flynn, who joined the Raiders via trade on Monday.

The Iowa State product was released by the Browns this offseason after backing up quarterbacks Brandon Weeden and Colt McCoy in 2012.
