According to ESPN, the Phillies announced today that All-Star second baseman Chase Utley will undergo surgery to repair his hip, and should be sidelined until June of 09.

As posted on ESPN.com:

According to the Phillies, Utley would be able to resume baseball activities in three to four months -- meaning sometime during spring training, but possibly not until the week before opening day.

However, full recovery time is projected at between four and six months. That means the best-case scenario is a return in early April, but the worst-case scenario is late May or early June, depending on how long a rehab option the club feels he would need.
