Former UFC middleweight champion Evan Tanner (32-7 MMA, 11-5 UFC) and “The Ultimate Fighter 3” middleweight winner Kendall Grove (8-5 MMA, 3-2 UFC), two fighters coming off disappointing losses, will meet in the main event of “The Ultimate Fighter: Team Rampage vs. Team Forrest’s” live finale.

The event takes place June 21 at The Palms Las Vegas and airs on Spike TV.

The UFC confirmed the Tanner vs. Grove fight over the weekend. The news conflicts an earlier report that a Diego Sanchez vs. Luigi Fioravanti fight would headline the event.

However, the UFC also confirmed the Sanchez vs. Fioravanti fight, which will presumably take place on the night’s televised main card.

Tanner returned from a two-year absence and suffered a second-round knockout to Yushin Okami at UFC 82 last month. Soon after the loss, Tanner wrote a blog entry about overcoming alcohol addiction so he could return to the UFC. He said he was both thankful and relieved that the defeat didn’t cause him to relapse and looked forward to future UFC fights.

Grove, the middleweight winner of “The Ultimate Fighter 3,” began his UFC career with three consecutive vitories. However, he’s since posted back-to-back losses—both of which were first-round knockouts—to Patrick Cote and Jorge Rivera.

Although Tanner vs. Grove and Sanchez vs. Fioravanti are now official, the UFC has yet to confirm bouts previously reported: Spencer Fisher vs. Jeremy Stephens, Josh Burkman vs. Dustin Hazelett, and Marvin Eastman vs. Drew McFedries.

The live finale will also include a fight between the two finalists of “The Ultimate Fighter: Team Rampage vs. Team Forrest.”
