TAMPA — Yankees pitcher Phil Hughes has upper back stiffness and will be sidelined for a few days.

“There’s always a little bit of concern, but it’s upper back by his shoulder blades, so we’ll see how he is in a couple days,” manager Joe Girardi said Tuesday. “You’re usually more concerned about the lower (back problem) lingering. The good thing is he was ahead of where he’d probably normally be at this time, which helps.”

Hughes was hurt Monday during a defensive drill covering first base.
