There wasn't an audible gasp when

LeSean McCoy

walked off the field clutching his wrist yesterday.

But the Eagles surely held their collective breath when the rookie running back was injured on the same day star tailback Brian Westbrook underwent surgery.

The good news for the Eagles was that X-rays were negative and that McCoy had just sprained his left thumb. Still, the setback could force McCoy out of some, if not all, of next week's organized team activities.

"It will be treated conservatively," Eagles trainer Rick Burkholder said. "If everything goes well this weekend, he's got a chance to practice next week."

Coach Andy Reid didn't sound as concerned.

"It's just his thumb," Reid said. "We'll splint that up and he'll go on. We won't worry about that."

With Westbrook to miss the rest of the activities as a result of ankle surgery, McCoy was scheduled for more repetitions with the first-team offense.

McCoy, who was receiving treatment after practice, was not available for comment, according to a team spokesman.

During one-on-one drills, the rookie out of Pittsburgh caught a pass from Donovan McNabb, moved upfield, and slipped. McCoy used his left hand for support, but jammed it on the turf inside the indoor facility at the NovaCare Complex.

Frick and Frack

McNabb and

Asante Samuel

, two of the more press-shy Eagles, continued their practice banter yesterday.

McNabb has been the offense's mouthpiece, while Samuel has countered for the defense.

After McNabb threw a touchdown pass during one-on-one drills, the quarterback teased Samuel. "It's been a bad day for the white," McNabb said, referring to the color of the defense's jerseys.

After Samuel deflected a McNabb pass to linebacker Stewart Bradley for an interception, the cornerback squawked and danced with his teammates, much to McNabb's dismay.

McNabb will host his ninth annual All-Star Kid's Clinic at the NovaCare Complex today. Tonight, he will host his annual White Party (guests must wear white) in town to raise money for his foundation, which tries to aid the American Diabetes Association, among other causes.

Long time, no see
