Tyler Thornburg underwent Tommy John surgery earlier this week, according to Bobby Nightengale of the Cincinnati Enquirer.
Thornburg recently went on the 45-day injured list for a right elbow sprain, but it’s news that he required major elbow surgery to correct the injury. Relievers can sometimes work their way back from Tommy John surgery faster than starters, but it’s still up in the air whether the soon-to-be 32-year-old will get back at some point in the 2021 season. It’s been tough sledding injury-wise for Thornburg during his major league career, as he also underwent thoracic outlet syndrome surgery a few years ago.
