Rising middleweight contender Antoine Douglas had to wait five days, but he learned the identity of his new opponent on Tuesday.

Antoine Douglas will take on Avtandil Khurtsidze in a 10-round bout on March 5 at the Sands Casino in Bethlehem, Pennsylvania, in the co-main event of a Showtime-televised tripleheader that is headlined by Julian “J Rock” Williams (21-0-1, 13 KOs), 25, of Philadelphia, will meet Marcello Matano (16-1, 5 KOs).

Douglas lost his opponent Sam Soliman last week, but found a game foe in Khurtsidze who has a had relatively good career with most notably a loss to Hassan N’Dam in 2010.

Last week, former middleweight world titleholder Sam Soliman (44-13, 18 KOs), of Australia, withdrew from the fight because of a nagging knee injury, leaving organizers to search for a new opponent to face Douglas (19-0-1, 13 KOs), 23, of Burke, Virginia.

The main event between Williams and Matano will be for the mandatory challenger at the 154-pound world titleholder Jermall Charlo (23-0, 18 KOs).

Tony Harrison (22-1, 18 KOs) will open the broadcast against Fernando Guerrero (28-3, 20 KOs).
