What happened: Sean Strickland defeated Khamzat Chimaev via split decision (48-47, 47-48, 48-47) at UFC 328 to reclaim the middleweight title. Strickland survived an early wrestling onslaught to outstrike the previously unbeaten Chimaev over five rounds in Newark.

Why it matters: The victory cements Sean Strickland as the sport's ultimate spoiler, winning his second title as a 3-1 underdog or longer. He handed Chimaev the first loss of his professional career while reclaiming the gold he lost earlier this year.

What to watch: Strickland is expected to headline a major card for his first title defense later this year. Chimaev will likely look for a top-five opponent to regain title contention.
