"An Indianapolis Colts offense already operating at less than full strength because of injuries might have taken another hit during Friday afternoon's practice at Anderson University.

Pro Bowl tight end Dallas Clark was unable to finish the workout after injuring his left leg while running a pass route. There was no immediate comment on the severity of the injury.

After stutter-stepping his feet to stay inbounds near the back of the end zone, Clark pulled up lame. He walked slowly toward a sideline, flexing his left leg before being met by a trainer.

Clark was taken to a treatment tent near the practice field, finally emerging with a wrap around his upper left leg. He didn't return to practice and left a few minutes early on a cart.

The injury might prove to be minor. If not, it would be the latest setback to the offense.

Pro Bowl center Jeff Saturday could miss up to six weeks after arthroscopic knee surgery, while starting left tackle Charlie Johnson missed all week of practice with a sprained right foot. Rookie interior lineman Jacques McClendon also missed this week's work with an undisclosed injury."
