Lions coach Jim Caldwell said "all options are open" when it comes to finding a backup quarterback. Shaun Hill signed with the Rams, leaving only Kellen Moore behind Matthew Stafford.

Moore has not appeared in a regular-season game, and it's unclear if he has a legitimate shot at the No. 2 job.

“We keep looking and we could certainly address it a number of different ways, and all options are open at this time,” Caldwell said, per the Detroit Free Press.

Signing Dan Orlovsky is one possibility. He started seven games for the Lions from 2005-08.
