Giants defensive end Jason Pierre-Paul had surgery for a sports hernia and what the team called a core muscle injury on Wednesday morning and will probably be sidelined for about six weeks, according to people with knowledge of Pierre-Paul’s condition who were not authorized to speak publicly about it.
The injury is expected to keep Pierre-Paul, a two-time Pro Bowler and the Giants’ most disruptive defender, out for the remainder of the regular season and probably through the first two weeks of the N.F.L. playoffs, should the 8-4 Giants qualify for the postseason.
The Giants, however, did not announce a timetable for Pierre-Paul’s return.
