Conor McGregor's highly anticipated return lasted just six seconds before a non-contact right knee injury brought his comeback to an abrupt end.
After planting and changing direction, McGregor's right knee appeared to buckle, leaving him visibly compromised. Despite the obvious instability, he attempted to continue fighting before the bout was ultimately stopped.
According to ProFootballDoc's video analysis, the injury mechanism raises significant concern for damage to the ACL and MCL. The footage also suggests the possibility of a patellar subluxation, or partial kneecap dislocation, which can occur alongside ligament injuries and further compromise knee stability.
Pro Football Doc said a recently resurfaced video of Conor McGregor struggling to remove his shoe before his fight does not prove the former UFC champion entered the bout with a preexisting knee injury, but it also does not rule out the possibility. He said the footage is consistent with someone who could have been dealing with a right knee ligament injury, though it is not evidence that McGregor had an ACL tear before the fight. Despite McGregor's insistence that he entered the bout healthy, Pro Football Doc said that statement alone is not definitive, noting McGregor could have sustained an injury without realizing its severity. He said several scenarios remain plausible, including the ACL injury occurring entirely on the flying kick, a preexisting injury being aggravated by the kick and landing, or the injury existing before the fight.
While a definitive diagnosis will require MRI imaging and a full medical evaluation, the video evidence points to significant structural damage in the right knee.
McGregor's willingness to continue fighting despite the apparent injury was remarkable. Attempting to compete on a potentially unstable knee with multiple damaged structures speaks to his toughness, even if his comeback ended almost as soon as it began.
