CLEVELAND — The Browns are searching for a new coach, general manager — and Johnny Manziel.

His weekend itinerary remains a mystery.

The team doesn’t seem to know whether their polarizing second-year quarterback, who sustained a concussion last week in Kansas City, went to Las Vegas on Saturday as his teammates got ready for their season finale.

Manziel was not going to play Sunday against the Pittsburgh Steelers because he’s in the NFL’s protocol on head injuries. Club owner Jimmy Haslam wasn’t sure of the 23-year-old’s whereabouts.

“I’m not exactly sure where Johnny is,” Haslam said Sunday night. “Haven’t talked to him. I know our football people will be on top of that.”
