UFC Fight Night 78 (21 nov)

Less than three weeks before their fight in Mexico, Matt Brown is out of his welterweight main event against Kelvin Gastelum.

Brown (20-13 MMA, 13-7 UFC) told FOXSports.com‘s Damon Martin he suffered an ankle injury that will knock him from the headliner against Gastelum (11-1 MMA, 6-1 UFC) later this month. UFC officials have not yet made an announcement of the injury or if a replacement will step up to fight Gastelum on short notice.

Less than 24 hours after officially weighing in at 145 pounds for his first UFC featherweight fight, Diego Sanchez is apparently now 26.2 pounds heavier.

In other words, the UFC Fight Night 78 headliner has rehydrated more than a pound an hour ahead of tonight’s event.
