Four men walked away from UFC on Fox 2 with post-fight bonuses on Saturday night, as Lavar Johnson Evan Dunham and Nik Lentz each took home an extra $65,000 from the United Center in Chicago.Johnson (Pictured, file photo) was awarded “Knockout of the Night” after flooring Joey Beltran with a series of uppercuts, while Oliveira captured “Submission of the Night” for his first-round finish of Eric Wisely . Dunham and Lentz garnered “Fight of the Night” honors for their hard-fought two-round scrap.BR> Johnson, a five-time Strikeforce veteran, sent Beltran a message early in their heavyweight showdown, punishing “The Mexicutioner” with a body shot in the bout’s opening moments. He controlled the action from there, using an effective jab to keep Beltran on his heels. The 34-year-old finished the fight with authority -- dazing Beltran with an uppercut followed by a right hook -- before landing more uppercuts in the clinch to send the Alliance MMA representative face first to the canvas at the 4:24 mark.Making his first appearance at 145 pounds, Oliveira quickly went to work on Wisely, attacking the UFC rookie with crisp leg kicks. When Wisely attempted a kick of his own, “Charles do Bronx” caught it and stood over his opponent, searching for an opening. Oliveira then dropped for a heel hook that looked to have Wisely in trouble, but the 27-year-old Iowan appeared to escape danger by twisting out of the move. The Brazilian didn’t relinquish hold of Wisely’s leg, however, and Oliveira’s persistence paid off as he converted the position into a modified calf slicer. Wisely asked out of the bout at 1:43 of the first period.After a back-and-forth opening frame where Lentz landed several takedowns and showed aggressive standup, Dunham asserted his will in round two of their lightweight tilt. After a spirited exchange between the two men on the feet, Dunham scored a takedown and battered the Minnesotan with elbows and punches. By the time the frame expired, Lentz’s left eye was nearly closed due to the punishment he received. Prior to the third round, a ringside physician determined that “The Carny” could no longer continue, and Dunham emerged with the technical knockout triumph.
