Overview
- McGregor’s comeback lasted 69 seconds at UFC 329 when his right knee buckled during an opening jumping kick and referee Mike Beltran stopped the bout.
- The fighter announced he will have surgery and a rehabilitation program and said he aims to return to finish the final fight on his UFC deal.
- UFC president Dana White and promotion doctors are publicly 'assuming' a torn ACL but formal imaging and a surgeon’s report have not been released.
- Viral video showing McGregor apparently limping into a pain clinic four days before the fight has renewed questions about a pre‑existing problem, a claim McGregor and his coach deny.
- The injury deepens durability concerns for the 37‑year‑old, complicates a possible April 2027 return and leaves UFC scheduling, public reaction and retirement talk unresolved.
