Back to where he once belonged: Sanchez returns to Jackson's

UFC veteran Diego Sanchez is back home again. "The Nightmare" has returned to Jackson's MMA in New Mexico, where he first trained after winning the first season of "The Ultimate Fighter." He Tweeted on Tuesday that, "It's official I'm 100% back at team jackson's about to gear up and spar.. My heart is very warm at the moment."

As he trains for the UFC 121 match with Paulo Thiago, Sanchez is already working with famed coaches Greg Jackson and Mike Winkeljohn. Sanchez was part of a core group of fighters that included Nate Marquardt, Rashad Evans, Keith Jardine and Georges St. Pierre. They've since added Clay Guida, Jonny "Bones' Jones, Donald Cerrone, Leonard Garcia, among other top fighters.

Sanchez is on a two-fight skid, so a change isn't the worst idea. B.J. Penn beat Sanchez like he owed him money, and then John Hathaway shocked Sanchez in a decision.
