Connor Zilisch underwent collarbone surgery Tuesday morning, the No. 88 JR Motorsports driver announced on social media.
The 19-year-old NASCAR Xfinity Series star broke his collarbone Saturday afternoon in Victory Lane at Watkins Glen International after scoring his sixth win of 2025. After climbing from the cockpit of his No. 88 Chevrolet, Zilisch slipped and fell while standing on the roof and door of his car.
Zilisch was released from the hospital the same night and missed the Cup Series race on Sunday after being scheduled to pilot the No. 87 Chevrolet for Trackhouse Racing.
Wanted to give everyone a quick update. Had surgery on my collarbone this morning to get a plate and screws to help with the healing process. Been a tough few days for me mentally, but all the love you guys have shown has certainly helped. Thank you❤️

It’s the second time Zilisch has suffered an injury in his rookie campaign. He sat out the race at Texas Motor Speedway after a back injury following a last-lap wreck at Talladega Superspeedway the weekend prior. Kyle Larson piloted the No. 88 Chevy in Zilisch’s stead and won at Texas.
JR Motorsports has not announced if Zilisch will miss time as a result of the operation. The Xfinity Series will have a weekend off before heading to Daytona International Speedway on Friday, Aug. 22 (7:30 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio).
