Ivan Nova has a grade 1 strain:

New York Yankees right-hander Ivan Nova suffered a Grade 1 flexor strain in his right forearm in the second inning of Thursday’s ALDS Game 5, the team announced in a news release Friday.

Nova was examined by team physician Dr. Chris Ahmad at New York Presbyterian Hospital and underwent an MRI, which revealed the injury. The Yankees said they expected the injury to “heal without complications” during the winter.

With the Tigers winning, the Yankees have the luxury of time.
