Kelvin Gastelum vs. Neil Magny to headline TUF Latin America Finale with Matt Brown out

Neil Magny is back to his old ways.

The UFC welterweight, known for fighting as much as possible and filling in on short notice, will face Kelvin Gastelum in the main event of The Ultimate Fighter Latin America 2 Finale on Nov. 21 in Monterrey, Mexico, the UFC announced Tuesday. Matt Brown was to be Gastelum's opponent until he fell injured this week.

Magny (16-4) is coming off a split decision win over Erick Silva in August. Before that, the Elevation Fight Team product had his seven-fight winning streak stopped by Demian Maia at UFC 190 in August. Magny, 28, has already fought four times this year. In 2014, he fought five times.

Magny was supposed to fight Stephen Thompson at UFC 195 on Jan. 2. It's unclear if Thompson will remain on that card.

Gastelum (11-1) is moving back down to welterweight after a one-fight stint at middleweight and second-round TKO of Nate Marquardt at UFC 188 in June. He had a very bad weight cut before a UFC 183 loss to Tyron Woodley back in January. Gastelum, still just 24 years old, was the youngest winner of The Ultimate Fighter when he took the crown during the 17^th season.

The Ultimate Fighter Latin America 2 Finale will be the UFC's first trip to Monterrey. In the co-main event, Ricardo Lamas will meet Diego Sanchez and a bout between Henry Cejudo and Jussier Formiga is also on the card.
