ALLEN PARK, Mich. (AP) -- Lions quarterback Daunte Culpepper had an MRI on his shoulder, leading to doubt that he will play on the road against the Indianapolis Colts.
Detroit coach Rod Marinelli said Monday the team would wait for results of the exam before exploring other options for a starting quarterback.
After Culpepper was hurt, Drew Henson was sacked on the final play Sunday.
Dan Orlovsky hopes to be healthy enough to play this week after being out for a month with a wrist injury.
Drew Stanton has been sidelined for two weeks with a concussion, but is expected to be ready to play if necessary.
The Lions (0-13) will close at Indianapolis, against New Orleans and at Green Bay hoping to avoid being the NFL's first 0-16 team.
