Dan Campbell is the tight end whose versatility keeps defenses guessing. Pete Hunter is the cornerback who beat out three rookies to become the starter opposite Terence Newman.
Those were their job descriptions for the Cowboys _ until Wednesday, when both were declared out for the season because of injuries.
Campbell severely sprained his right foot and Hunter tore a ligament in his left knee, both during a victory over the Redskins on Monday night. They are scheduled for surgery Tuesday.
The Cowboys plan to put them on injured reserve once they're ready to sign their replacements, likely in time for practice today.
The only solace in the timing of the injuries was that it came during a bye week. Dallas next plays a week from Sunday, at home against the Giants.
"When you've got seven practices instead of three, that's a substantial difference," coach Bill Parcells said.
BILLS: Rookie quarterback J.P. Losman threw his first practice passes since breaking his left leg last month, and anticipates being cleared for contact within three weeks.
BROWNS: Offensive tackle Ryan Tucker and defensive lineman Gerard Warren will miss Sunday's game against Washington with injuries. Tucker is out for the second straight week with a strained quadriceps muscle. Warren sat out last week, too. He strained a chest muscle in the season opener against Baltimore and irritated it a week later. The banged-up Browns are hoping to have running back Lee Suggs and tight end Steve Heiden back against the Redskins.
DOLPHINS: Defensive tackle Tim Bowens, who has yet to play this season, will miss Sunday's game against the Jets with a herniated disc in his back. Receiver Chris Chambers didn't practice and was listed as questionable with a previously undisclosed knee injury. Middle linebacker Zach Thomas also sat out practice and is listed as questionable with a shoulder bruise. Miami signed free-agent running back Brock Forsey, a sixth-round pick of the Bears in 2003.
PANTHERS: Running back Stephen Davis will not play Sunday against the Falcons because of a knee injury. DeShaun Foster, who ran for 174 yards and a touchdown filling in for Davis two weeks ago, will start instead. Davis had arthroscopic surgery on his knee Sept. 17.
