UFC 183 Tyron Woodley vs. Kelvin Gastelum full fight video preview

It's the fight that almost didn't happen.

Strikeforce import Tyron Woodley will battle The Ultimate Fighter (TUF) 17 champion Kelvin Gastelum in the co-main event of tonight's (Sat., Jan. 31, 2015) UFC 183: "Silva vs. Diaz" pay-per-view (PPV) event, taking place inside MGM Grand Garden Arena in Las Vegas, Nevada.

Gastelum missed weight by a whopping nine pounds.

Nevertheless, the show must go on, and "The Chosen One" will now be awarded 30-percent of Gastelum's fight purse, which could add up to a nice chunk of change if he's victorious in "Sin City." Can Woodley overcome the current former middleweight?

Watch this preview and judge for yourself.

There's a lot on the line in tonight's 170-pound showdown. Not just for Woodley and Gastelum, but for the welterweight division, as well, which could be looking for a new set of title challengers in the latter half of 2015.
