Promotional efforts are underway for the Kevin Lee vs. Charles Oliveira main event at UFC on ESPN+ 28.

The key lightweight bout between Lee (18-5 MMA, 11-5 UFC) and Oliveira (28-8 MMA, 16-8 UFC) will headline the March fight card, and over the past few days the pair have been touring the city to build up hype for the event.

That included a number of faceoffs, the latest of which was particularly intense and featured a little physical contact, though everything remained relatively civil.
