24 hours after weighing 145 pounds, UFC's Diego Sanchez now at 171.2

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.

Sanchez today posted the following photo on Instagram at 2:30 p.m. ET, and assuming no trickery is afoot, he tipped the scale at a staggering 171.2 pounds. (Let that sink in for a moment: He’s put on more than 26 pounds in less than a day.)

Here’s what he looked like at weigh-ins:

Sanchez, who looked a bit depleted (and understandably so) at Friday’s weigh-ins, meets featherweight contender Ricardo Lamas (15-4 MMA, 6-2 UFC) tonight at the FOX Sports 1-televised event. UFC Fight Night 78 takes place at Monterrey Arena in Monterrey, Mexico.

Sanchez, who won the first season of “The Ultimate Fighter 1” as a middleweight more than a decade ago, looks to become the first UFC fighter to win bouts in four different weight classes.
