The first live Premier Boxing Champions on ESPN (PBC on ESPN) telecast will be headlined by a 12-round welterweight bout between undefeated contender Keith Thurman and former titleholder Luis Collazo, the network announced on Thursday. The new monthly series debuts on ESPN on Saturday, July 11, at 9:00 p.m. ET.

Thurman (25-0, 21 knockouts), THE RING’s No. 5-rated welterweight, is coming off a unanimous decision over Robert Guerrero in March. Collazo (36-6, 19 KOs), a 34-year-old veteran southpaw, scored a second-round TKO over Christopher Degollado in April to rebound from a unanimous decision loss to Amir Khan last May.

The opening fight of the broadcast will showcase a 10-round junior middleweight matchup between undefeated Tony Harrison (21-0, 18 KOs) and Willie Nelson (23-2-1, 13 KOs). ESPN3 will also carry live the preliminary bouts at a time to be determined. The card will be held in Tampa, Fla., at a site to be named.
