"The Red Sox might be losing one of their most valuable players.

According to the Boston Globe, Dustin Pedroia is heading to Boston today for an examination of his right knee, which might need surgery.

"It could keep me out a month," the star second baseman told the Globe. "It's not what I want. But I have to get it checked out. It's been bothering me a lot."

The second baseman has struggled this season, but is considered one of Boston's emotional leaders. According to the report, Pedroia's knee has been hurting since May 16 against Baltimore. He also was limited to just 75 games last year because of injuries."
