World Series of Fighting 31 takes place in Mashantucket, Connecticut, and it's a pretty solid card in store for fans tonight on NBC SN. Reigning heavyweight champion Blagoi Ivanov defends his belt against UFC veteran Josh Copeland in the main event, while fellow UFC vets Jason High and Mike Ricci square off in a lightweight co-main event, with the winner in line for a title shot.
Also featured on the main card is an exciting featherweight matchup between Luis Palomino and Sheymon Moraes, middleweight prospect Phil Hawes against Joshua Key, and former UFC fighter John Howard debuting in WSOF against Michael Arrant.
