ALLEN PARK, Mich. -- The winless Detroit Lions probably will be without starting quarterback Daunte Culpepper against the surging Colts. Culpepper did not practice Wednesday, three days after injuring his shoulder.
"It's more doubtful than probable," coach Rod Marinelli said when asked about Culpepper's status.
Marinelli said an MRI on Culpepper's shoulder revealed a sprain.
Culpepper stretched with teammates Wednesday, then left the field and had to avoid a blocking sled a teammate was hitting toward him.
Orlovsky has been out since Nov. 2 with an injured wrist.
"It felt structurally strong. It felt better," he said. "I'm going to miss some throws because of it, but I'm pretty confident I'll be able to go out and play effectively."
Stanton has been sidelined since Nov. 23 with a concussion.
"I feel good now," he said.
Henson threw an NFL pass on Thanksgiving for the first time in four years and was sacked on the final play Sunday against the Vikings after they knocked Culpepper out of the game.
The Lions (0-13) seem destined to be the NFL's first 0-16 team, closing against the Colts, New Orleans and Green Bay.
Indianapolis, which has won six straight, is favored to win its 10th game of the year by more than two touchdowns against Detroit.
