The Dallas Cowboys will be without starting wide receiver Terry Glenn for Sunday's road game against the Arizona Cardinals.

Glenn

ESPN.com confirmed Saturday evening that Glenn, who did not practice Wednesday or Thursday and worked only lightly on Friday because of a knee injury, did not accompany the Cowboys on their charter flight and has been ruled out of the game.

Glenn, 32, had been listed as "probable" all week on the Cowboys' official injury report, but that was clearly an optimistic assessment of his condition.

It was not yet known if Patrick Crayton or rookie Sam Hurd will replace Glenn as the starter opposite wide receiver Terrell Owens.

The likely choice is Crayton, who has 17 receptions for 259 yards and two touchdowns and typically plays as the No. 3 receiver. But the three-year veteran is also frequently used on punt returns and coach Bill Parcells has tried not to overwork him. Hurd has one catch for 33 yards.

An 11-year veteran, Glenn is suffering from a condition known as chondromalacia, a roughening of the cartilage on the underside of his right kneecap. He has been able to to play through the pain so far this season. The knee has worsened over the last two or three weeks and Glenn was forced to cut short his work on Friday because of discomfort.

With the knee still not responding well to treatment, the decision was made Saturday to leave Glenn behind and give him the weekend to rest.

Glenn has the second-most receptions on the Dallas roster through eight games, 36, for 456 yards and four touchdowns. Even at age 32, Glenn remains a viable deep threat. His career average is a healthy 14.7 yards per reception and he has 31 catches of 40 or more yards in his career.
