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).

Luke Weaver's twinge was felt by the entire New York Yankees fan base. The closer went on the 15-day injured list Tuesday with a strained left hamstring, two days after he got hurt while warming up during a 7-3 victory at the Los Angeles Dodgers.

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.
