Overview
- McGregor tore an ACL in his July 2026 rematch with Max Holloway, a knee injury that ended the fight after roughly 69 seconds.
- Longtime coach John Kavanagh says McGregor is rehabbing aggressively, is "moving around quite well," and may be able to begin MMA‑type training in 2027.
- McGregor remains in testing pools and has one fight left on his UFC contract, so any bout outside the UFC would require him to clear or exit that deal.
- Kavanagh has accepted an ambassador‑style role with the new Ki MMA promotion, which creates a potential non‑UFC pathway but does not change McGregor’s current contract status.
- McGregor’s prior 2021 leg break, his age, and advances in sports medicine shape the comeback outlook and will influence whether he returns to high‑level competition or shifts to one-off events.
