Meathead returns!

Former Ultimate Fighter (TUF) 10 contestant Matt Mitrione, who vowed to improve after losing a unanimous decision to Cheick Kongo at UFC 137 last October, will finally get his chance when he slugs it out against Philip De Fries at the UFC 155 scheduled for Sat., Dec. 29, 2012, in Las Vegas, Nevada.

Wait, what?

Mitrione was originally scheduled to face off against Rob Broughton, first at UFC on FOX 4 back on Aug. 4 in Los Angeles before Broughton was forced to put things on hold to clear up a few "personal issues," then at UFC on FX 5 on Oct. 5 in Minneapolis.

But that's not happening anymore, according to the UFC, for reasons that are still unclear.

Mitrione (4-1) saw his perfect record go up in smoke against the powerful Parisian, but prior to that, had amassed an impressive list of victims that included four devastating stoppages by way of knockout.

Can he get back into the win column against the British submission specialist?

For his part, De Fries (9-1) is coming off a second round rear-naked choke submission win over Oli Thompson at UFC on Fox 4 earlier this month, giving him two victories in three tries inside the Octagon.

Take care of business against Mitrione and who knows where things could go.

UFC 155 will be headlined by Heavyweight Champion Junior dos Santos defending his title in a rematch against the man he took the belt from, Cain Velasquez. In addition, Chael Sonnen returns to the 205-pound division to battle former champ Forrest Griffin.
