The Ultimate Fighter (TUF) 17 champion Kelvin Gastelum (-165) is still the odds-on favorite to beat TUF 6 veteran Matt Brown (+145) when they collide in the main event of UFC Fight Night 78, set for Nov. 21, 2015 at Arena Monterrey in Monterrey, Mexico.
Gastelum (11-1) returns to the welterweight division after a quick pit stop at middleweight, prompted by a pair of failed weight cuts. While there, the Arizonian beat the stuffing out of Nate Marquardt at UFC 188, running his Octagon record to 6-1 with three finishes.
Brown (20-13), meanwhile, is looking to build on his submission win over Tim Means at UFC 189.
