The surgery Brian Westbrook will undergo Friday 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 ESPN.com Wednesday.
