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 in Tampa. ‘‘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.’’
