MMAmania.com (www.mmamania.com) learned this afternoon that season five winner of The Ultimate Fighter (TUF), Nate Diaz (7-2), will return to the Octagon against Alvin Robinson (9-2) at UFC Fight Night 12 on January 23.

The Caesar Gracie Jiu Jitsu-trained Diaz is fresh off a submission win (guillotine) over Junior Assuncao at UFC Fight Night 11 in September. It was his first bout since defeating Manny Gamburyan at the TUF 5 Finale to become the 155-pound winner of the mixed martial arts reality series that airs on SpikeTV.

Robinson bounced back from a punishing loss to Kenny Florian (verbal submission) in his Octagon debut at UFC 73: "Stacked" to beat Jorge Gurgel to a bloody pulp at UFC 77: "Hostile Territory" last month en route to a unanimous decision win.

Both Diaz and Robinson are well known for their submission games; however, the edge on the ground would have to go to Diaz in this one -- he's very crafty. "The Kid," on the other hand, is very strong and powerful.
