Unbeaten light heavyweight Thomas Williams Jr. steps up to face veteran Gabriel Campillo in a 12-round main event headlining ESPN's "Friday Night Fights."

Williams (17-0, 12 KOs), nicknamed "Top Dog," enters the fight from the Little Creek Casino Resort in Shelton, Washington, (ESPN2, 9 p.m. ET) as a highly ranked prospect. Meanwhile, his opponent Campillo (23-6-1, 10 KOs) is a former titlist looking to get back on track after losing three of his last five.

A native of Fort Washington, Maryland, Williams will undoubtedly be the fighter to watch closely considering the great expectations his career has drawn and his position in the rankings of three major sanctioning bodies. At 26, Williams enters the bout coming off two spectacular performances in 2014.

On Jan. 24, he got up off the canvas in the first round to finish Cornelius White before the round ended. In his most recent bout on April 24, he stopped Enrique Ornelas in the third round.

Campillo, 35, a native of Spain, who is managed by former world middleweight champion Sergio Martinez, held a light heavyweight title from 2009 until losing it the following year by split decision in his rematch with Beibut Shumenov. He lost another controversial title bout by split decision against then-titlist Tavoris Cloud in 2012.

In 2013, Campillo suffered a pair of stoppage losses to future titlist Sergey Kovalev and Andrzej Fonfara. He bounced back in May with a stoppage win against Ricky Dennis Pow in Spain.

The co-main event offers a second pairing of southpaws as former world title challenger Andre Dirrell (21-1, 14 KOs) returns to action after 18 months in a 10-round super middleweight bout against Vladine Biosse (15-4-2, 7 KOs).

Dirrell, 30, hasn't fought since a unanimous-decision win over Michael Gbenga in February 2013 in Texas. He is best remembered for his participation in the Super Six super middleweight tournament, where he suffered his lone career defeat at the hands of Carl Froch by split decision in 2009.

Biosse, 32, a former football player from the University of Rhode Island, enters the bout fresh off a pair of defeats. He lost to Britain's Callum Smith in Liverpool, England, on July 12 after a February defeat against J'Leon Love.
