New York Yankees right-hander Ivan Nova has tightness in his right shoulder and will fly back to New York on Thursday for tests.
Nova, the losing pitcher Tuesday night against the Chicago White Sox, said he felt something in his shoulder while making a sixth-inning pitch to Alexei Ramirez, the final batter he faced in the Yankees' 7-3 loss. Nova threw 84 pitches in his six innings, giving up six runs and seven hits.
After a strong start this season, Nova is 11-7 with a 4.92 ERA but is just 1-4 with a 7.28 ERA in his last eight starts.
David Phelps would be a candidate to replace Nova in the rotation if he has to miss his next start.
