Martin Kampmann (20-6 MMA, 11-5 UFC) welcomed Carlos Condit (28-7 MMA, 5-3 UFC) into the octagon four years ago with a split-decision loss, and now Condit will have a chance to earn his revenge.

FOXSports.com today reported that the welterweights are set to rematch in a headlining bout at UFC on FOX Sports 1 2, which takes place Aug. 28. at Bankers Life Fieldhouse (formerly Canseco Fieldhouse) in Indianapolis.

The event’s main-card airs live on FOX Sports 1. Broadcast plans for the preliminary card have yet to be announced.

Condit and Kampmann first met at UFC Fight Night 18 in April 2009. Condit was making his octagon debut after a stint as the welterweight champ of the WEC, which shuttered its 170-pound division before closing up shop in 2010. After three closely contested rounds, Kampmann earned the nod on two judges scorecards by scores of 29-28 while one judge scored the fight 29-28 for Condit.

Condit, who is ranked No. 4 in the latest USA TODAY Sports/MMAjunkie.com MMA welterweight rankings, is coming off back-to-back losses for the first time in his UFC career. He won the interim championship against Nick Diaz at UFC 143 and went on to challenge undisputed champ Georges St-Pierre, who unanimously outpointed him at UFC 154. He then took on top contender Johny Hendricks at UFC 158 and lost another unanimous decision.

In a previous interview, Condit took aim at a rematch with Diaz, which he said would silence critics of his UFC 143 win. But he said he first wanted to shore up weaknesses in his wrestling game to which he attributed his high-profile setbacks.

Diaz, though, remains retired and has no plans to fight, his rep Jonathan Tweedale today told MMAjunkie.com (www.mmajunkie.com).

Kampmann, who is ranked No. 9, aims to get back in the winner’s circle after a quick knockout loss to Hendricks at this past November’s UFC 154, which ended a second bid for a welterweight title shot. Prior to the loss, he won three straight, including a KO win over top contender Jake Ellenberger.
