LAS VEGAS (June 15, 2016) –World Series of Fighting (WSOF.com) announced today that Thiago Meller has withdrawn from his scheduled welterweight (170 pounds) contest against John “Doomsday” Howard (23-12), who will now face“Mad” Mike Arrant (15-10) in a middleweight (185 pounds) bout at the much-anticipated WSOF31: Ivanov vs. Copeland world championship doubleheader Mixed Martial Arts (MMA) event, live on NBCSN (9 p.m. ET/6 p.m. PT) from Foxwoods Resort Casino in Mashantucket, Conn. on Friday, June 17.

In addition, undefeated Marcus Surin (3-0) of Stamford, Conn. has been tabbed to step in for Sam Watford in the scheduled lightweight (155 pounds) preliminary card contest against Christian “The Terminator” Torres (0-0) of Endicott, N.Y.

Originally hailing from Orlando, Fla., the 5-foot-9, 28-year-old Arrant, a Brazilian Jiu-Jitsu brown belt, resides in Las Vegas, where he is a member of legendary champion Randy “The Natural” Couture’s Xtreme Couture fight squad.

Arrant is looking to return to the win column following a unanimous decision defeat in his last start on August 7, 2015, at the hands of two-time UFC veteran Brock Jardine.

Prior to the loss, Arrant had reeled off six consecutive victories, five of which he produced in the first round, by way of (T)KO or submission.  To date, 12 of his 15 professional wins have been finishes.

During the six-fight win streak, Arrant seized his first championship – regional promotion SteelFist Fight Night’s welterweight title – with a first round (5:00) TKO (retirement) of Carl Dieckmann on July 12, 2013.

Like Arrant, the 5-foot-7, 33-year-old Howard boasts a phenomenal finish rate with 15 of his 23 professional victories having come by way of (T)KO or submission.

Howard will make his promotional debut with World Series of Fighting following a second stint with the UFC that spanned seven fights and included wins over Uriah Hall, Siyar Bahadurzada and Cathal Pendred.

Priced from $39.99, tickets for WSOF31: Ivanov vs. Copeland are on sale at WSOF.com and Foxwoods.com.

Doors at The Grand Theatre at Foxwoods Resort Casino will open at 5 p.m. ET, and the first of seven preliminary card bouts will begin at 5:45 p.m.

The entire preliminary fight card will stream live on an embeddable video player on WSOF.com.

In the main event of the five-bout, live NBCSN telecast, reigning World Series of Fighting heavyweight champion Blagoy Ivanov (13-1) will put his title on the line against Josh “Cuddly Bear” Copeland (12-3).

In the lightweight co-main event, superstars Jason “The Kansas City Bandit” High (19-5) and Mike “The Martian” Ricci (11-4) will square off with their division’s number one contender ranking at stake.
