The third chapter between former UFC lightweights Frankie Edgar and B.J. Penn will be written in the desert. The duo will headline The Ultimate Fighter season 19 Finale on July 6, according to a report from Ariel Helwani on UFC Tonight.

The longtime rivals will first coach season 19 before competing at the event.

The two fought twice in a span of four months in 2010.

When they first met at UFC 112 in April of that year, Edgar was a huge underdog, but using his superior speed, he shocked Penn in a mildly controversial but unanimous decision that earned him the UFC title. They rematched in August, and again Penn was favored. Edgar won again, in a victory that was far more decisive, as he out-landed Penn 142-56 overall.

Edgar, 32, went on to hold the belt for another year-and-a-half before losing to Benson Henderson. He’s 16-4-1 all-time.

Meanwhile, since facing Edgar last, the 35-year-old Penn (16-9-2) would win only one of his next four fights before falling into a short semi-retirement, announcing his return last year with the intention of gaining revenge on Edgar.

The TUF 19 Finale is expected to be held at the Mandalay Bay Events Center, just one day after UFC 175 takes place at the same arena, marking the first time the UFC would hold back-to-back nightly events at the same venue.
