Davie, Fla. ? The Indianapolis Colts added defensive end Robert Mathis and cornerback Jason David, both starters, to the injury report Friday after their last full practice before the Super Bowl.

Mathis left practice early because of back spasms and was listed as probable. David, who has battled a nagging abdomen injury this season, sat out the entire practice and was listed as probable.

Safety Bob Sanders and guard Ryan Lilja, also starters, took the day off, but both are expected to play.

Coach Tony Dungy said Mathis should play Sunday.

“He’s fine,” Dungy said. “He left as a precaution.”

Indy’s other starting cornerback, Nick Harper, has been listed as questionable all week with a sprained left ankle. He missed practice again Friday, and Dungy said he would be a game-time decision.

“We decided it didn’t make any sense for him to go out and try to practice today,” Dungy said. “We’ll wait to see how Nick feels on Sunday at the stadium.”
