Fact Check: World Series of Fighting 31

Blagoy Ivanov has yet another chance to further cement himself as the top heavyweight in the World Series of Fighting.

Ivanov will defend his heavyweight title against former Resurrection Fighting Alliance champion Josh Copeland in the WSOF 31 headliner on Friday at the Foxwoods Resort Casino in Mashantucket, Connecticut. Their five-round battle will shoulder the marquee for a five-fight main card that includes a Jason High-Mike Ricci co-main event, a featherweight clash pairing Luis Palomino with Sheymon da Silva Moraes, a middleweight scrap pitting Phil Hawes against Joshua Key and a welterweight tilt matching John Howard with Michael Arrant.

A 5-foot-11, 250-pound brute who survived a near-fatal stabbing in 2012, Ivanov has rattled off back-to-back victories since submitting to an Alexander Volkov rear-naked choke under the Bellator MMA banner more than two years ago. The 29-year-old last fought at WSOF 24 on Oct. 17, when he stopped Derrick Mehmen with second-round punches to retain his heavyweight championship. Wins over Smealinho Rama, Lavar Johnson, Rich Hale, Kazuyuki Fujita and former Ultimate Fighting Championship titleholder Ricco Rodriguez bolster Ivanov’s resume.

Copeland, 33, operates out of the Grudge Training Center in Colorado, where he trains alongside undefeated WSOF lightweight champion Justin Gaethje. The “Cuddly Bear” has gone 3-1 since being released by the UFC following consecutive losses to Ruslan Magomedov and Jared Rosholt. Copeland sports eight finishes among his 12 professional victories.
