With Frankie Edgar in his rear-view mirror, Benson Henderson is now set for his second title defense as lightweight champion. That bout will come against former The Ultimate Fighter winner Nate Diaz in the main event of UFC on Fox 5.
In addition to the lightweight title fight, Saturday's event will also feature an important 205-pound bout between former champion Mauricio Rua and rising Swede Alexander Gustafsson. Rua has been less than impressive as of late, while Gustafsson has quickly made his way up the light heavyweight rankings and is looking to earn a title shot.
Furthermore, B.J. Penn will return to the Octagon for the first time in more than a year. His opponent, Rory MacDonald, has become a 170-pound contender and is looking for the signature win that could put him in the running for a championship bout.
A fight between exciting welterweights Mike Swick and Matt Brown will complete one of most impressive main cards to ever air on free television.
Before Saturday's event, which will take place at KeyArena in Seattle, the fighters will hit the scales on Friday at 4 p.m. ET. Video of the weigh-ins will be streamed live on the above video player.
