What happened: Sean Strickland defeated Khamzat Chimaev via split decision (48-47, 47-48, 48-47) in the main event of UFC 328 at the Prudential Center. Strickland weathered early wrestling pressure to outwork the previously undefeated champion over five rounds, marking the first professional defeat of Chimaev's career.
Why it matters: The victory cements Strickland's status as a premier spoiler, having now secured two of the biggest upsets in UFC title history as a underdog. The result validated Luke Rockhold's claim that Strickland would be Chimaev's toughest test at 185 pounds.
By the numbers: Strickland out-landed Chimaev 160-137 in total strikes despite yielding 6:04 of control time and nine takedowns. Closing saw Strickland as a significant underdog against the favorite. Strickland is the only fighter since 2008 with multiple title wins as a 3-1 underdog or longer.
What to watch: Strickland expressed interest in facing Alex Pereira next, while Chimaev will likely look to regroup after losing his undefeated record and the belt.
