CC Sabathia left today's game in the second inning due to left biceps tightness.
From the AP:
A team trainer went out to look at Sabathia while he was warming up for the inning. He gave up a one-out double to Brett Carroll, then Yankees manager Joe Girardi and a team trainer went out to check on the left-hander again before taking him out of the game.
The reliable Alfredo Aceves took over for him, but this sounds like bad news for Sabathia.
More on the injury later.
