Johnny Walker Books Heavyweight Debut vs. Mick Parkin at UFC 332

Johnny Walker is reportedly set to make his heavyweight debut at UFC 332, targeted for October 3 in Salt Lake City, Utah, against No. 15-ranked Mick Parkin. According to reports, the matchup would be the first bout added to the UFC 332 card, though it has not yet been officially confirmed.

Walker, 34, arrives at heavyweight after a career spent at light heavyweight, where he holds a 22-10 record and currently sits ranked 12th in that division. The Brazilian out of SBG Ireland stands six-foot-six with an 82-inch reach — measurements that may translate more naturally to the heavier weight class. He lands 4.06 significant strikes per minute at a 55 percent accuracy rate, and the move up comes after his previously scheduled heavyweight debut against Ante Delija at UFC Belgrade fell through when Delija was forced to withdraw.

Parkin, 30, is an English heavyweight representing TFT MMA who carries a 10-1 record and is currently ranked 15th in the division. Standing six-foot-four with a 79-inch reach, he lands an impressive 4.7 significant strikes per minute at 50 percent accuracy and adds 1.38 takedowns per 15 minutes, giving him a well-rounded threat profile. Parkin trains alongside UFC heavyweight champion Tom Aspinall, the 33-year-old Englishman who holds a 15-3 record and the divisional title.

Why it matters

• Walker's first career appearance at heavyweight is a notable divisional crossover, pitting a long-time light heavyweight contender against an established heavyweight prospect.

• Walker's size — particularly his 82-inch reach — could be a factor against heavyweight competition, making the stylistic test an intriguing one.
• The bout is reported as the first official addition to the UFC 332 lineup, giving the October card its first named matchup.
