Hughes getting treatment for bulging disk

"I'm convinced I'll be symptom-free in the next four or five days," Hughes said Wednesday. "I felt like I was kind of ahead of the game with my throwing. I threw a bunch of bullpens before I got here, and thankfully it's early enough in spring, it's a setback, but I still have a lot of time to get it right."

Yankees general manager Brian Cashman said it could be two weeks before Hughes could resume throwing off a mound.

"Obviously, it's something you wish you weren't dealing with, and hopefully it's nothing major," Cashman said. "We'll know within the next two weeks. The expectations and the hope from that is that he'll be fine and ready to go. But there's no guarantees until we get through the two weeks' process and see where he's at. We won't be out of the woods until we see all that stuff."

The right-hander had an MRI on Tuesday, one day after experiencing discomfort in his upper back during a defensive drill.
