NEW YORK -- 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.
Weaver was hurt Sunday while warming up at the Los Angeles Dodgers. He is projected to be sidelined for four to six weeks. The PRP is designed to speed healing.
"He was out already throwing yesterday. He'll be doing his throwing program today," New York manager Aaron Boone said before Friday's series opener against the Boston Red Sox.
