BALTIMORE -- The Yankees are mulling how to proceed with their rotation in the wake of an injury to right-hander Chad Green, who was diagnosed with a sprained right ulnar collateral ligament and a strained flexor tendon after being forced to leave in the second inning of Friday's 8-0 loss to the Orioles.
Manager Joe Girardi said that right-handers Bryan Mitchell and Luis Severino are among the choices who could be asked to fill in on Wednesday against the Blue Jays at Yankee Stadium, when Green's rotation slot is set to come around again. Girardi said that no decisions have been made.
"We're just going to play it by ear, and we're going to see where we're at, depending on what we need the next couple of days," Girardi said. "It could be a number of different scenarios we use on Wednesday, but I think what you have to worry about now is the game that's in front of you."
Mitchell started for Triple-A Scranton/Wilkes-Barre on Thursday, throwing 91 pitches over 5 1/3 innings while holding Buffalo to a run and four hits. Mitchell walked none and struck out six.

While Girardi said that the Yankees have discussed giving Mitchell one more start at Triple-A, Severino pitched a scoreless inning on Friday, and the Yankees may not want to move him back to the rotation.
"You may get to a situation where you decide to start Sevvy or something where he's built up, but I do want to have Sevvy available [in relief] for these games, because I think they're important games," Girardi said.
Green, 25, -- ranked by MLBPipeline.com as the Yankees' No. 21 prospect -- will be examined by team physician Dr. Christopher Ahmad when the Yankees return to New York after Sunday's series finale. He is 2-4 with a 4.73 ERA in 12 games (eight starts) this season.

Girardi said that he is frustrated to see another injury to a pitcher, particularly one the Yankees tried to handle carefully. Including his Minor League stats, Green worked 140 2/3 innings this year. He had pitched 148 2/3 innings for Double-A Erie in 2015, when he was property of the Tigers.
"You do everything you can to protect them, and it doesn't seem to work. It is frustrating," Girardi said. "For Chad, it wasn't necessarily one pitch, which you see with some guys. But you look at his innings, his innings are similar to last year. It's not like this year was a stretch, but it's just hard to figure out."
While Green is disappointed to be dealing with an injury at this point of the season, the rookie expressed some relief that he might be able to avoid the worst-case scenario of Tommy John surgery, something he said was on his mind as he walked out of Camden Yards on Friday.
"It's always nice to know that I probably, hopefully, won't need surgery," Green said. "Maybe just some rest will be good. We'll see what happens."
