Bryce Harper may not play right field for the Philadelphia Phillies until late July.

Harper has sat out the club's last three games after having a platelet-rich plasma injection in his right elbow.

He had the injection Sunday because of a small tear in the ulnar collateral ligament of his throwing elbow that has forced him into the role of designated hitter. He hasn't played right field since April 16 and will remain as DH whenever he returns.

Joe Girardi said Wednesday that doctors said Harper should not throw for at least six weeks.

"I think he has some real clarification. I think it kind of put him at peace, actually," Girardi said. "I think knowing that he has to wait, there's not much he can do until six weeks anyway. He'll just focus on hitting. I think the concern for the player is when it comes closer to actually trying something out."
