Ivan Nova told reporters on Wednesday that he felt a “grab” in his pitching shoulder during Tuesday night’s outing in Chicago, and the 25-year-old righty is being sent back to New York for testing.

Nova, who was touched up for six runs on seven hits in six innings last night, said he felt the grab while pitching to his final batter on Tuesday night, and then told the team today that he felt soreness and stiffness in his right shoulder.

This isn’t the first injury scare for Nova over the last week, as he appeared to tweak his groin or ankle in the fourth inning of his last start against Texas last Thursday, but ultimately stayed in the game. Nova has struggled since the All-Star break, posting a 1-4 record and a 6.89 ERA in his last nine starts through Tuesday, but told reporters that he had never felt anything in his shoulder before.

According to manager Joe Girardi, Nova will likely miss at least one start. Going to the disabled list is a possibility, and if that is the case, it would end speculation on what could have been a tricky pending roster move for the team later this week.

The Yankees are set to activate CC Sabathia (elbow) from the DL to start on Friday in Cleveland, meaning someone would have to be deactivated; multiple reports earlier Wednesday hinted that the team was considering sending Joba Chamberlain, who himself has struggled mightily since returning from Tommy John surgery on July 31, down to Triple-A to work out the kinks – but if Nova is to be out for any extended period of time, he could just be sent to the DL when Sabathia is activated, with Phelps instead taking his spot in the rotation.
