Harvin, who was supposed to have the operation on Tuesday, posted on Twitter:

The surgery was to clean out bone spurs.
Harvin battled health issues for much of 2011. He had rib and finger injuries to go along with a sprained AC joint (shoulder).
According to 1500ESPN.com, it is not known how this postponement affects Harvin's readiness for practices, which begin on May 29.
It's been a rough week for Harvin, who was implicated in stories about the downfall of the Florida Gators football program.
