Overview
- Walker scored a first-round knockout of Mick Parkin in his heavyweight debut at UFC 332 on Oct. 3, using a knee to finish the fight.
- The Brazilian is already back in training and has told media he has asked to face Marcin Tybura on the UFC 335 card in Las Vegas, a reported request that has not been confirmed by the promotion.
- Tybura is a long-tenured UFC heavyweight with past wins over names like Andrei Arlovski and Tai Tuivasa but arrives at the potential matchup on a three-fight losing streak dating to March 2025.
- Walker says he requested Tybura because he wants measured, lower-risk fights to learn the division before stepping up to higher-ranked opponents and because he no longer has brutal light‑weight cuts.
- Any bout for December would still need UFC matchmaker approval, contract and medical clearance, and if booked the fight would give Walker a chance to build a heavyweight resume while offering Tybura a possible route back toward the top 15.
