The UFC is turning more than a few heads today, as it’s announced that Kelvin Gastelum has been granted permission to return to welterweight, and that he’ll fight Matt Brown next. How about that?

The promotion has confirmed that the fight will be the main event for the November 21st, UFC Fight Night 79, which will take place in Monterrey, Mexico.

Of course, the reason the fight’s caught some folks off guard, is because it wasn’t long ago when the UFC moved Gastelum to middleweight, as a result of his well documented, weight cutting issues. In January, Gastelum (11-1) came in nearly 10 pounds over weight for his scrap with Tyron Woodley, and after losing by split decision, he was moved to 185.

In June, Gastelum dominated Nate Marquartdt for the stoppage win, and afterwards, he asked for the opportunity to fight at welterweight once more. Dana White didn’t exactly seem to be on board with the idea, but here we are.

The 5# ranked Brown is looking to build on his submission win over Tim Means at UFC 189. Prior to the win, “The Immortal” dropped back-t0-back decisions to Johny Hendricks and Robbie Lawler.
