Playing quarterback for the Cleveland Browns is proving a challenging, and short-term, job this season.
Cody Kessler, starting because of injuries to Robert Griffin III and Josh McCown, left Sunday's 33-13 loss to New England after hurting his ribs and chest in the first quarter.
Kessler was hurt when hit on a backward pass that went out of the end zone, giving the Patriots a safety.
That brought in veteran backup Charlie Whitehurst playing for his fifth NFL team, and he hobbled to the sideline in the final minutes after hyperextending his right knee.
