The Cleveland Browns have signed veteran quarterback Tyler Thigpen, and he'll now begin preparing to play Sunday against the Ravens, according to a league source.
The Browns attempted to convince quarterback Rex Grossman to sign with them, but a source said he declined their offer.
Browns rookie quarterback Connor Shaw took the first-team snaps in practice Tuesday and is preparing to start. Thigpen is expected to back him up.
Johnny Manziel is out for the season with a significant hamstring injury and Brian Hoyer is dealing with a shoulder injury.
Thigpen, who was with the Browns during the preseason before being released, has passed for 3,222 career yards, 21 touchdowns, and 18 interceptions for a 72.5 quarterback rating. He also has rushed for 469 yards and three touchdowns.
Thigpen has played for the Kansas City Chiefs, the Buffalo Bills and the Miami Dolphins. He played in college at Coastal Carolina.
