Delhomme was injured a week ago against Atlanta and hasn't practiced since, although as the No. 3 QB, he was dressed for the game.
Coach John Fox said last week that Delhomme didn't need surgery, although a team spokesman backed down from the statement Sunday, saying only that surgery isn't planned and Delhomme's status is being evaluated daily.
Carr, a five-year starter in Houston, was signed in the offseason to provide Carolina with a more reliable backup than last year's No. 2 quarterback, Chris Weinke. He led Carolina on two scoring drives in relief of Delhomme in the win over the Falcons.
Middle linebacker Dan Morgan (ankle) was on Carolina's inactive list. His backup, Adam Seward (calf), also did not dress. James Anderson replaced him in the starting lineup.
