The Philadelphia Eagles’ thin receiving corps received a major blow when starter Todd Pinkston was lost for the season Friday with a ruptured right Achilles’ tendon.

Pinkston was injured when he was tripped up on a route down the sideline.

He remained down for several minutes before limping to the medical tent.

The Eagles were practicing without All-Pro receiver Terrell Owens. He’s day-to-day with left groin inflammation.

“We feel bad from a team standpoint for Todd,” coach Andy Reid said. “He worked very hard this offseason. He was having a heck of a camp, and it’s a shame this happened.”

The six-year veteran averaged 18.8 yards per catch, third in the league.

“For a guy that doesn’t complain, that works extremely hard and really never receives credit for the things that he does for this team … it’s tough,” quarterback Donovan McNabb said. “We’ve all been injured, but this kind of an injury, with surgery – you never know what can happen afterwards.”

Reid said the team would not look to sign another receiver.

Philadelphia eagles wide receiver Todd Pinkston leaves the playing field with a season-ending injury. Pinkston ruptured an Achilles' tendon at practice Friday at training camp in Bethlehem, Pa

“We’re fine,” he said.

Reid said third-year pro Greg Lewis would move into Pinkston’s spot on the first team. Last year, Lewis had 17 receptions for 183 yards in limited action and also caught a touchdown pass in the Super Bowl.

“Todd is one of the closest friends I have on the team, and I feel bad for him for all the work he’s put in this offseason,” Lewis said.

“But injuries take place in this game, and the team has to get in there. Somebody has to step up and make plays.”

The Eagles also have Billy McMullen, a third-round pick in 2003. Rookie Reggie Brown had been competing with McMullen to be the fourth receiver.

Running back Correll Buckhalter also went down with a leg injury in the morning practice in Bethlehem, Pa. The team said he had a bone bruise. Buckhalter missed all of last season after tearing a tendon in his right knee during the preseason. He missed all of the 2002 season with a knee injury.

Dallas Cowboys

Marcus Spears could miss a month after spraining his right knee and ankle and pulling his groin. Spears, a defensive lineman, was limping after a play during 11-on-11 drills and went to the sideline.

Owner Jerry Jones said team doctors told him that Spears would need four weeks of rehabilitation for the sprained knee, during which time the other injuries also should heal.

Spears was drafted 20th out of LSU.

Arizona Cardinals

Wide receiver Anquan Boldin is expected to miss two to three weeks of practice after breaking his nose.

“I would think he’s going to be out at least two preseason games,” coach Dennis Green said Friday at camp in Prescott, Ariz. “We’re just happy that it’s not real serious – there’s a lot of pain, obviously. And he should be as good as new.”

Boldin, who also burst a blood vessel in his nose, was at camp in street clothes and said doctors realigned his nose.

Boldin will be re-evaluated Wednesday.

Boldin was injured Thursday when cornerback Aaron Francisco inadvertently hit his head, causing Boldin’s helmet to slam hard into his nose.

The third-year receiver from Florida State set an NFL record for receptions by a rookie in the 2003 season, catching 101 balls for 1,377 yards. He was honored as the league’s offensive rookie of the year and invited to the Pro Bowl.

New York Jets

Quarterback Chad Pennington was held out of practice for the second time in three days as he rested his surgically repaired right shoulder.

Pennington, held out Wednesday by coach Herman Edwards after practicing for five straight days, threw some sharp passes in the team’s session Thursday night.

He was 9-of-17 during the practice, including 6-of-11 in 11-on-11 drills.

More important, Pennington showed some zip on a few passes – something that generally had been lacking the first few days of camp.

Edwards said he planned to have Pennington participate in the Jets’ workout with the Giants in Albany, N.Y., today.

Tennessee Titans

Negotiations with Tennessee’s top top draft pick, Adam “Pacman” Jones, are stalled, and Titans general manager Floyd Reese isn’t sure when a deal for the cornerback will be reached.

The general manager said Jones’ agent wanted to address the language of the contract. The Titans have said they want to include clauses to protect themselves. Jones, the sixth pick overall in the draft, has a court date Thursday on vandalism and two misdemeanor assault charges.

San Francisco 49ers

Receiver P.J. Fleck was taken by ambulance to Stanford Hospital after a practice collision that sent a scare through San Francisco’s camp. Fleck was hit by linebacker Jamie Winborn during 7-on-7 passing drills and was on the ground about 15 minutes while trainers and paramedics attended to him.

Fleck was taped onto a backboard and placed on a gurney and wheeled to an ambulance. He was diagnosed with a back sprain and later released.

“It scared me to death,” Winborn said. “It scared everybody.”

Bills, Packers scrimmage

Packers quarterback Brett Favre finally got the Lambeau Field crowd of 62,492 pumped up by throwing three short touchdown passes in the span of four plays inside the Bills’ five-yard line.

The only other score while the first-teamers were on the field came on a 12-yard jaunt by Bills running back Willis McGahee, who ran 12 times for 32 yards.

Favre hit tight end Ben Steele twice and wide receiver/kick returner Antonio Chatman for the TDs.
