The surgery Brian Westbrook will undergo tomorrow morning in Baltimore is a serious procedure, according to a source close to the situation.

"I'm just concerned that it is being underplayed," the source said. "It's a lot more than a little spur and it's much more than the knee arthroscopy he had (in February)."

Both a team source and Westbrook's agent Todd France downplayed the significance of the surgery, which the team announced late Wednesday night.

"It's just some bone spurs," France told Wednesday.

The agent also described the surgery as "minor" and a team source said it wasn't "a major procedure."

Exactly how serious Westbrook's surgery will be won't be known until after Dr. Mark Myerson completes the procedure. Only Myerson can give a clear timetable of how long it will take Westbrook to recover and he won't be able to do that until after he has seen the extent of the damage in the running back's right ankle.

The Eagles continued their camp this morning with Lorenzo Booker getting the majority of snaps with the first-team offense. The third-year running back talked about Westbrook afterward.

"Brian played with those injuries all last year and now he's getting a chance to clean it up," Booker said. "That's one of the tougher guys I've ever been around, so I don't see him missing any significant time. He's going to miss the things that he can afford to miss, which is the preseason and OTAs. What can he possibly learn or prove in the preseason?"
