Terry Glenn hurt

IRVING, Texas -- Dallas Cowboys receiver Terry Glenn left practice early Friday after apparently aggravating his injured right knee, making him unlikely to play Sunday at Arizona.

Coach Bill Parcells had said Glenn probably wouldn't play if he didn't practice Friday, and undrafted rookie Sam Hurd was lining up with the starters during a walk-through even before Glenn was hurt.
Glenn, who had missed two days of practice because of irritation under his kneecap, reached for a pass during a drill early in practice. But he left the field hobbling and slammed his helmet to the floor of the Cowboys' practice building.
Glenn, in his 11th NFL season, has caught 36 passes for 456 yards and four touchdowns this season.
Before practice, Parcells was not saying who would replace Glenn if he couldn't play.
"I'm not dealing in hypotheticals," he said. "[Patrick] Crayton and Hurd can play that position.''
Hurd, out of Northern Illinois, won a roster spot with Cowboys during the preseason by catching 15 passes for 200 yards and a score. He has one catch for 33 yards this season.
Crayton, Dallas' third wide receiver, has caught 17 balls for 259 yards and two touchdowns.
