Arizona Diamondbacks right-hander Zac Gallen likely will miss the start of the regular season multiple medical tests confirmed that he has a hairline stress fracture in his pitching forearm.

Diamondbacks manager Torey Lovullo made the announcement about Gallen’s condition Tuesday, saying that two doctors reviewed the results of an MRI exam, a CT scan and an X-ray.

No ligament damage was found, which Lovullo called “the best news possible.”

The manager added regarding the timeline for Gallen’s return, “We’re just going to get through this first phase, where he’s playing catch, and then reload, and I’ll keep you guys updated.”

The injury occurred while Gallen was taking batting practice on March 10. He subsequently threw 3 1/3 shutout innings in a Cactus League game on March 12, then gave up three runs in 4 1/3 innings on March 17, but he hasn’t pitched since.
