From The Athletic: According to McCullers, doctors believed the flexor tendon injury he sustained in October would heal in time for the season. But in late January or early February, after his offseason throwing program was underway, he didn’t feel 100 percent healthy. More doctors visits and tests revealed that his tendon just hadn’t quite healed, and another round of platelet-rich plasma (PRP) and stem cell therapy followed. *** McCullers said he had his PRP therapy about three weeks ago and his stem cell therapy about a week ago. Surgery has not been discussed, he said, adding the doctors he’s consulted with are confident the tendon issue will resolve itself. He also said he’s had it “confirmed about four or five times from a bunch of different doctors, including (Neal) ElAttrache” that it’s not an ulnar collateral ligament issue. ElAttrache, a renowned orthopedic surgeon based in Los Angeles, did McCullers’ Tommy John surgery in November 2018.
