Tim Tszyu vs. Tony Harrison to air on Showtime on March 11

It was announced on tonight’s Showtime Championship Boxing telecast that Tim Tszyu, son of boxing legend Kostya Tszyu and an undefeated action fighter, will return to his birthplace of Sydney, Australia to face former world champion Tony “Superbad” Harrison for the vacant Interim WBO 154-pound title in the main event of a Showtime telecast live on Saturday, March 11 (Sunday, March 12 in Australia).

Tonight’s Showtime tripleheader kicks off at 9 p.m. ET/6 p.m. PT and features undefeated two-division champion Rey Vargas meeting top contender O’Shaquie Foster for the vacant WBC Super Featherweight World Championship in the main event from the Alamodome in San Antonio in an event presented by Premier Boxing Champions.

The winner of Tszyu-Harrison is in line for a prized shot at undisputed super welterweight king Jermell Charlo. Tszyu (21-0, 15 KOs) elected to face the veteran Harrison, a highly skilled, crafty fighter after Tszyu’s scheduled match with Charlo on January 28 was scratched when Charlo broke his hand in training.

Harrison (29-3-1, 21 KOs) edged Charlo in 2018 to capture a world title before he dropped their rematch a year later. In his last fight, Tszyu rose from a first-round knockdown to dominate former title challenger Terrell Gausha last March in his U.S. debut.

Now Tszyu, 28, will face another prideful veteran as he tries to revisit his match with Charlo, while Detroit’s Harrison, 32, hopes to spoil Tszyu’s homeland return and gain a third fight with Charlo in a matchup that will be announced tonight.
