There are some intriguing match-ups on tonight’s WSOF 4 card in Ontario, California, including the promotional debut of undefeated lightweight Nick Newell. The former XFC champion and one armed fighter has gone 9-0 in his MMA career to date, and has understandably generated a ton of buzz as a result.

Newell recently spoke with MMA about tonight’s tilt, which will see him take on another rising lightweight in Keon Caldwell (9-1). The 27 year-old fighter had this to say about fighting for WSOF, which has a significant promotional stage via its broadcast deal with the NBC Sports Network.

“It is a big stage and the stakes are high. I am super excited to debut. It is awesome man, I can’t wait to show everyone what I can do.”

“Definitely, there’s a lot more attention and a lot more media but it comes with the territory when you move to a bigger league and have bigger fights. More people paying attention, more media, more interviews but I don’t mind.”

Newell hasn’t competed since December, when he tapped out Eric Reynolds under the XFC banner. Caldwell, meanwhile, hasn’t fought since July, 2011, when he stopped Jonathan Baldree at a Southerneastern Fighting Champions event.

“He’s tough,” Newell said about Caldwell. “Definitely one of my toughest fights. He is young and a great athlete, also hits like a truck.”

WSOF 4 will go down at the Citizen’s Business Bank Arena and will be broadcast on the aforementioned NBC Sports Network beginning at 10:30 PM / ET. The card will be headlined by a light-heavyweight tilt between Tyrone Spong and Angel DeAnda.
