Berea, Ohio — Their starter has a sore shoulder, bruised ribs and who knows what other ailments.

Their backup could be facing NFL discipline.

The Browns quarterback situation — always convoluted — is even more of a mess.

With Josh McCown unable to throw because of a right shoulder injury sustained last week in St. Louis, Cleveland officials don’t know yet if he’ll be able to start Sunday when it hosts Arizona.

And McCown’s injury isn’t the team’s only concern.

Johnny Manziel, who replaced McCown in the fourth quarter against the Rams, met Wednesday evening with league investigators, who are looking into whether he violated the personal conduct policy during an Oct. 12 argument with his girlfriend.

According to an Avon, Ohio, police report, Colleen Crowley accused Manziel of hitting her and pushing her head against his car’s window during their argument.

Cleveland coach Mike Pettine confirmed league officials hopes to have their inquiry wrapped up quickly.

“There’s a sense of urgency to it,” Pettine said.
