Hyun Jin Ryu's 2022 season is officially over.
The Toronto Blue Jays left-hander will undergo left elbow surgery, general manager Ross Atkins announced Tuesday, according to TSN's Scott Mitchell.
The exact procedure has yet to be determined, but he'll either have a partial UCL reconstruction or Tommy John surgery to repair a damaged ulnar collateral ligament. If Ryu needs full-scale Tommy John, his 2023 season could also be in jeopardy.
