Yankees pitcher Phil Hughes is likely out for two weeks because of a bulging disc in his back, reports YES's Jack Curry and others on Twitter.
The 26-year-old Hughes went 16-13 with a 4.23 ERA in 32 starts last season.
Hughes has battled injuries over the past few seasons. Last year, he was pulled from his start against Detroit during Game 3 of the ALCS because of a stiff back. He has also previously battled "dead arm." He missed a large portion of the 2011 season after his velocity dropped, and some worried the injury might threaten his career.
