The New York Yankees are going to try everything to bring first baseman Mark Teixeira back this season, but it may not be enough.

If Teixeira, who was placed on the 15-day disabled list Saturday with torn articular cartilage in his right knee, doesn't respond to rest, Cashman says potentially season-ending surgery may be required.

"The initial effort is going to try to be to treat it conservatively with rest, probably involving injections, and then see how he responds to that," Cashman told Chad Jennings of Lohud.com. " ... If that doesn’t work, then you’re looking at a surgical procedure. If that’s the case, then his season is probably done."

Losing Teixeira long term would be a devastating blow to the Yankees, who have suffered a myriad of injuries over the early part of the season. They're particularly thin at first base, though, as his two would-be replacements, Greg Bird and Dustin Ackley, are both already out for the rest of 2016.
