Browns' Griffin clears concussion protocol, could play Sunday

Cleveland Browns quarterback Robert Griffin III has cleared the NFL's concussion protocol and could play Sunday, the team announced.

Griffin exited Saturday's win over the San Diego Chargers in the fourth quarter, giving way to rookie Cody Kessler.

Before leaving, he was having his best game of the season, finishing with 164 yards on 17-of-25 passing.

Though he hasn't exactly impressed this year, at least one member of the Browns thinks Griffin could be a long-term answer at quarterback.

''We've got a limited amount of film on him so far, but I think the things we've seen in meeting rooms, on the practice field, in some of the games, I think you've seen franchise-level talent for sure, and I wouldn't write him off by any stretch of the imagination,'' left tackle Joe Thomas said Wednesday, according to The Associated Press.

"I wouldn't be shocked at all if he was our guy at the beginning of next season because I think he has shown enough that if they do decide to make Robert the guy, I think he can definitely be the guy, and I think he'd have the support of the locker room."
