Koda Glover may not pitch for the Washington Nationals anytime soon.

Glover, who has been on the disabled list with lower back stiffness, revealed Wednesday that he has "severe inflammation of the rotator cuff and two strains" in his right shoulder.

There is no timetable for Glover's return, but he hasn't been cleared to start throwing yet.

"It's obviously frustrating," he said. "You want to play. It's what you wake up to do. It’s your job. But it's one of them things where it's kind of out of your control. I'm just doing what I can to get healthy and be back as soon as possible."
