The UFC 280 hangover on Saturday swings into full gear with the Ultimate Fighting Championship’s return to the UFC Apex in Las Vegas, even though there is plenty to like about UFC Fight Night 213. It starts with the main event: a featherweight pairing between Calvin Kattar and Arnold Allen that serves as an excellent bout in one of the promotion’s best divisions and the most important test to date for the latter participant. As far as the rest of the five-fight main draw goes, the clear other standouts are a banger of a welterweight co-headliner between steady vets Tim Means and Max Griffin, along with the opener, which sees Dustin Jacoby take a surprisingly risky but potentially violent matchup against Khalil Rountree at 205 pounds.
