So the mysterious bone bruise wasn't the problem after all.

With his bruise healed but his pain persisting, sidelined closer Jonathan Broxton has decided to undergo a minor elbow operation Monday to shave down a bone spur and remove loose bodies.

Broxton went on the disabled list in early May, when an MRI exam showed he had a bruised elbow and bone spur. Figuring the bruise was responsible for Broxton's pain, team physician Dr. Neal ElAttrache prescribed rest.

The two-time All-Star made enough progress to pitch in a couple of minor league games in July, but had to be shut down when the pain returned.
