Chase Utley said he plans to accompany the Phillies on their trip to St. Louis, which begins Thursday, pushing back his departure for Florida even further.

The decision is particularly noteworthy as today marks the one-year anniversary of Utley's 2011 regular-season debut, after he sat out all of spring training and the first seven weeks of the season with a similar knee injury.

Throughout the spring and early season, he's insisted the pain he's felt in his left knee this year isn't as bad as what he endured in his right knee in 2011, an injury that forced him to miss the first seven weeks of the season.
