Johnny Walker Set for Heavyweight Debut Against Mick Parkin at UFC 332

Johnny Walker is moving up to heavyweight for the first time in his UFC career to face Mick Parkin at the Delta Center. The three-round bout was originally scheduled after Walker's previously planned heavyweight debut against Ante Delija did not materialize. Walker, who stands 6'5" with an 82-inch reach, previously competed at light heavyweight at 206 pounds.

Mick Parkin enters the matchup with an UFC record that includes four wins and a single loss to Marcin Tybura in March 2025. While Walker brings significant experience with a 22-10-1 record and a history of knockouts, Parkin has established a tactical approach centered on control and pacing. The upcoming fight presents a test of how Walker’s durability and movement transition to the heavyweight division against a natural heavyweight opponent.
