Los Angeles Rams quarterback Matthew Stafford is unlikely to play Sunday against the Green Bay Packers as he deals with a thumb injury. Stafford suffered a ulnar collateral ligament sprain in his right thumb in last week's loss to the Dallas Cowboys. If Stafford is ruled out, Brett Rypien would replace him as the starter with Dresser Winn as the backup.
