Sources: Shoulder surgery for McCourty

Patriots defensive back Devin McCourty underwent surgery on his shoulder earlier this offseason, but he is expected to be ready for the start of training camp, according to multiple sources.

It is not known on which shoulder McCourty had the surgery performed. In 2011, McCourty played through a separated right shoulder.

The surgery was considered routine, aimed at strengthening the shoulder, and was performed shortly after the Patriots lost in the AFC Championship Game, sources said. While McCourty is expected to be ready for the start of training camp, the surgery has naturally affected his offseason, adding a rehabilitation element to it.

McCourty, one of the team’s captains, has been one of the Patriots’ most durable players since being picked in the first round of the 2011 draft out of Rutgers. Starting at cornerback as a rookie, he earned Pro Bowl honors after totaling six interceptions, then dipped a bit in his second season.

Last year, he moved to safety on a near-permanent basis after the sixth week of the season, and that could be his long-term home in New England.
