Brian Cashman didn't have much on the good-news front Tuesday afternoon.

The general manager said Nathan Eovaldi, diagnosed with right elbow inflammation Monday, very well may be done for the rest of the regular season -- and is questionable for the playoffs, as well -- and the same goes for injured first baseman Mark Teixeira.

Eovaldi said he experienced discomfort immediately after his start Saturday, and when there was no improvement by Monday morning, he was sent for tests at NewYork-Presbyterian Hospital. An MRI showed the inflammation.

"I was really surprised because he had had no problems before," manager Joe Girardi said. "Nothing."

Doctors gave Eovaldi, the team's leader in victories (14), innings pitched (1541/3) and starts (27), a platelet-rich plasma (PRP) injection and recommended he be shut down for two weeks and then begin a two-week throwing program.

That calendar eliminates the 25-year-old from pitching in the regular season and makes even an October return uncertain.

"Until he goes through a successful rehab, you can't automatically assume anything," Cashman said. "He has an issue that needs to be taken care of, so our medical team has put the proper time frame in place to try to address that. If it takes longer, it takes longer.

"The most important thing right now is having him be healthy . . . We just have to give him a timeout now and make sure that we put him in a position to be that asset again. Hopefully, it will be this year."

Eovaldi expects to pitch again this season and would even accept a bullpen spot if that's what is assigned.

Cashman said the Yankees still intend to insert a sixth starter in the rotation to give the other starters some extra rest, saying reliever Adam Warren, a starter earlier in the season, likely will be tabbed, though he'll be able to give only 45-50 pitches in his first outing.

As for Teixeira, out except for one game since Aug. 17 with a right shin bone bruise, Cashman did not sound optimistic about a return in 2015. ""I do wonder [if he'll be back]," Cashman said. "Again, first and foremost, it's been a long time and he's still having issues."

Teixeira, 35, remains on crutches and saw another specialist Tuesday, receiving "a few more injections" in the affected area, Cashman said.

"He's still feeling nerve issues running up and down the leg when he puts pressure on the leg," Cashman said. "We have to wait it out. No guarantees."
