in the main event of the UFC 155 Facebook fights, Todd Duffee returns to the UFC after a near three year absence, a surprising addition to the heavyweight roster after fighting just twice in the last two years.

The 27-year-old made his August 2009 UFC debut an impressive one, knocking out Tim Hague in just seven seconds -- one of the fastest KOs in promotion history. However, he was surprisingly cut after a third round KO loss to Mike Russow in May 2010.

Later that year, Duffee (7-2) lost in 19 seconds to Alistair Overeem in a New Year's Eve event in Japan. He returned after a long absence this past May with a 34 second TKO win over Neil Grove in the second event for the Super Fight League.

For his return, he gets the 26-year-old De Fries (9-1-0-1), an England product that is 2-1 thus far in his Octagon career. After debuting in November 2011 with a decision win over Rob Broughton, he was knocked out in 43 seconds by Stipe Miocic in February. De Fries rebounded with a second round submission win over Oli Thompson in August.

Of De Fries' nine wins, eight have come by submission. Duffee has never been submitted, but all seven of his wins have via knockout.
