Heavyweights will collide in \u201cRain City.\u201d<\/p>\n
MMAmania.com<\/a> confirmed with multiple sources today (Thurs., Jan. 8, 2026) that No. 10-ranked<\/a> Ultimate Fighting Championship (UFC) Heavyweight Marcin Tybura will take on surging Brazilian prospect Valter Walker at UFC Seattle<\/a> on Sat., March 28, 2026, inside Climate Pledge Arena in Seattle, Washington.<\/p>\n Walker (15-1) stumbled out of the gate in his UFC debut, suffering a loss to Lukasz Brzeski in 2024. Since then, however, \u201cClean Monster\u201d has completely rewritten the narrative \u2014 and the UFC record books.<\/p>\n Walker opened 2025 by submitting Don\u2019Tale Mayes with a heel hook (watch highlights<\/a>), his second straight victory via the technique. Five months later, he followed it up with another first-round heel hook against Kennedy Nzechukwu (watch highlights<\/a>), setting a new UFC record for most consecutive heel hook submission wins with three.<\/p>\n But he wasn\u2019t finished.<\/p>\n At UFC 321 in Oct. 2025, Walker once again locked in a first-round heel hook \u2014 this time against Louie Sutherland \u2014 tying Rousimar Palhares for the most heel hook submissions (four) in UFC history while extending his own record for consecutive heel hook finishes (watch it<\/a>).<\/p>\n A win in Seattle would almost certainly vault Walker into the Top 10 of the Heavyweight rankings.<\/p>\n Tybura (27-10), meanwhile, will be defending his No. 10 spot when he steps into the cage. The Polish veteran went 1-1 in 2025, handing highly touted U.K. prospect Mick Parkin his first professional loss at UFC London before suffering a quick knockout loss to debuting Ante Delija at UFC Paris (watch highlights<\/a>), snapping a two-fight win streak.<\/p>\n Now 40 years old, Tybura is 5-3 over his last eight appearances.<\/p>\n Here are some other bouts currently scheduled for UFC Seattle:<\/p>\n Casey O\u2019Neill vs. Gabriella Fernandes<\/p>\n Alexa Grasso vs. Maycee Barber<\/p>\n Nicolle Caliari vs. Carol Fiori<\/p>\n
