"I'm used to the word 'out.'" But as always the show goes on... See you on March 30th. An upcoming battle with Sebastian for the ages. A time of unification... Then the big fish. Spence or Crawford," the Australian boxer wrote on his social media.

Tim Tszyu was supposed to fight Keith Thurman on March 30, but just yesterday it was reported that Thurman was injured and pulled out of the fight. Also yesterday it was reported that Sebastian became Tszyu's new opponent
