New York Yankees closer Luke Weaver received a platelet-rich plasma injection designed to speed healing in his injured left hamstring, according to the Associated Press (h/t ESPN).

Weaver was injured Sunday while he stretched in the Yankees bullpen after warming up to pitch the ninth inning of a 7-3 win over the Dodgers. When Weaver reported feeling a grabbing in his hamstring, the Yankees went with left-hander Tim Hill to close over the victory.

Yankees closer Luke Weaver had a platelet rich plasma injection in his injured left hamstring, and designated hitter Giancarlo Stanton is on track to start a minor league rehabilitation assignment next week.
