Boxberger will be out at least eight weeks after he underwent surgery Thursday to repair a torn abdominal abductor muscle, Roger Mooney of The Tampa Tribune reports.
While manager Kevin Cash believes the Rays will likely have more of a firm timetable for the injury in the coming weeks, this diagnosis comes as bit of a surprise considering the team initially considered it just a tight hamstring. Barring any sort of trade, the Rays are expected to use a closer by committee approach until Boxberger returns healthy, as the club has a plethora of bullpen arms including Alex Colome, Xavier Cedeno and Steve Geltz that could take the role over for the short term.
