Reds ace Hunter Greene will undergo surgery to remove bone chips from his right elbow today, per Gordon Wittenmyer of the Cincinnati Enquirer. The team is hoping to have him back at some point in July.

The Reds revealed late last week that they’d sent Greene for multiple waves of imaging and hoped to have further news early this week. Greene himself said at the time that he’s navigated bone spurs for some time but had recently received a clean MRI on his ulnar collateral ligament. Doctors hadn’t recommended surgery for the bone chips until this point. He experienced some pain late last season, and doctors recommended an injection at the time. That allowed Greene to have a normal offseason, but he experienced renewed discomfort upon ramping up in camp and will now head under the knife.

Greene is far from the only pitcher in MLB to pitch through some known bone spurs or loose bodies in his elbow. Most professional pitchers have some degree of wear and tear in their elbow and/or shoulder, be it bone chips or mild damage to a ligament, flexor tendon, rotator cuff, labrum, etc. Reds fans will surely feel frustration that the discomfort dates back to last season but is being address in 2026. Surgery is a last-resort option, however, and hadn’t been recommended until this latest wave of discomfort set in.

Losing Greene is a gut-punch for a Reds rotation that had looked like one of the game’s strongest, on paper. He was in line to start Opening Day and be followed by Andrew Abbott, Nick Lodolo, Brady Singer and one of Chase Burns or Rhett Lowder, both former top-10 picks in the draft and highly touted top prospects. Greene’s injury now opens the door for both Burns and Lowder to make the staff — particularly after Chase Petty was optioned yesterday — although left-hander Brandon Williamson remains in camp and could be an option as he returns from a 2025 season lost to injury.

More to come.
