BEREA, Ohio — Robert Griffin III’s comeback cracked.

Cleveland’s quarterback curse strikes again.

Griffin broke a bone in his left shoulder during the fourth quarter of Sunday’s 29-10 loss at Philadelphia and will miss at least eight games — and potentially the season — with an injury that leaves the Browns’ muddled QB situation as jumbled as ever.

The franchise’s 25th starting quarterback since 1999, Griffin, who signed with the Browns as a free agent in March in hopes of reviving a career that fizzled in Washington, got hurt while trying to run out of bounds.

Griffin was nearing the sideline when he was struck by Eagles rookie defensive back Jalen Mills.
