Update: As it turns out, Nova left the game with right elbow soreness. He wanted to stay in the game when Joe Girardi and the trainer, came out, but when Nova said that the issue was in his elbow, Girardi said, "you're done."

Nova is undergoing an MRI tonight at Tropicana Field, and we probably won't get the results back until tomorrow morning. 

Nova hasn't been great so far this season, but it would be a big loss for the Yankees if he has to miss an extended period of time because he has the ability to put things together to go on a very good stretch.

Obviously with pitchers going down to Tommy John surgery every other week, there is a good reason to be concerned with you hear that his elbow is bothering him.

Should Nova have to go on the DL, the most likely candidates to replace him are David Phelps, Adam Warren and Vidal Nuno. The Yankees could also decide to bring back Shane Greene, and it's even possible we could witness the return of Alfredo Aceves. However, that would require Nova going on the 60-day DL most likely, because the Yanks would need to clear a 40-man roster spot for Aceves.

Original: Ivan Nova left Saturday night's game against the Tampa Bay Rays in the middle of the 5th inning with an apparent injury.

Joe Girardi and the trainer made a visit to the mound in the middle of an at-bat, and even though Nova tried waiving them off, he eventually came out of the game.

Nova has dealt with arm injuries in the past, going on the DL with a triceps issue last year, a shoulder injury in 2012, and a elbow injury in 2011.

He was getting roughed up pretty badly through the first three-plus innings before beng taken out. He gave up four homeruns -- two to Ryan Hanigan, and one each to Will Myers and Evan Longoria -- and eight runs total on eight hits, with one walk.

Stay tuned here, because watching the game as this point is just too hard to do.
