Conor McGregor’s coach doubles down on dry ice theory causing horror ACL injury at UFC 329

John Kavanagh believes dry ice is the ‘only thing that makes sense’ for Conor McGregor’s brutal injury at UFC 329. McGregor returned to competition for the first time in five years against Max Holloway in July, but his comeback ended in just 69 seconds . The 38-year-old injured his knee in the opening exchange after starting the fight with a wild roundhouse kick and was unable to continue without landing a single strike.
