Mike Pettine is not sure if Johnny Manziel will start this week for the Cleveland Browns as planned after a photo and Instagram video surfaced of Manziel taken at a club.

Pettine said he is gathering information but called the latest incident around his quarterback "disappointing. Very."

"I want to sit down and discuss it before I do a knee jerk and go off on a tangent," Pettine said.

Manziel was at nightclubs in Austin, with one video showing him holding a bottle while he was signing along to a song.

Manziel said he spent Thursday and Friday night in Texas before attending the Michigan State-Ohio State game in Columbus on Saturday.

Manziel went to rehab last offseason to address alcohol issues.
