Sean Brady Pulls Out of UFC Vegas 124 Main Event

Sean Brady has withdrawn from his scheduled main-event fight against Gabriel Bonfim at UFC Vegas 124 because of an injury, MMA Fighting reported. The welterweight bout was set for November 7, 2026, at Meta Apex in Las Vegas. Waldo Cortes-Acosta vs. Johnny Walker is listed as the replacement main event. No further details have been given on the nature of the injury or when Brady might return.

Bonfim, a 29-year-old Brazilian, enters the weekend as the No. 5 welterweight with a 19-1 record. He is coming off a five-round unanimous decision over Belal Muhammad on June 6, 2026, and has won all three of his most recent recorded fights, including a second-round knockout of Randy Brown. He lands 4.61 significant strikes per minute at 46 percent accuracy and averages 3.6 takedowns per 15 minutes.

Brady, 33, is ranked sixth at welterweight and holds a 19-2 record. The American won a unanimous decision over Joaquin Buckley at UFC 328 on May 9, 2026, in his most recent recorded fight. Before that, he lost by first-round knockout to Michael Morales in November 2025, and he submitted Leon Edwards in the fourth round in March 2025. He averages 3.53 takedowns per 15 minutes and lands 55 percent of his significant strikes.

Walker, a 34-year-old Brazilian with a 23-10 record, most recently knocked out Mick Parkin in the first round at UFC 332 on October 3, 2026, a result that came only a month before the card.

Why it matters

• A matchup between the No. 5 and No. 6 welterweights is off the card, removing a ranked pairing from the top of the bill.
• The two were evenly matched in reach at 72 inches each, though Bonfim is three inches taller and four years younger.
• Both are grapple-heavy, with takedown averages of 3.6 and 3.53 per 15 minutes, which made the pairing a notable wrestling-based contest.
• The new main event is listed as Cortes-Acosta vs. Walker, shifting the focus of the card.
