Jack meets Haiti-born Canadian Jean Pascal and his latest match was a victory against Browne just to become the WBA champion.

There are two experienced boxers who meet when Jack, who before the loss against Browne had not lost in almost five years, is 35 years old while Pascal is a year older.

- He always comes to the ring to fight. He is a warrior like me, Jack writes in a reply to Twitter.

The match is about a so-called interim championship in the WBA as the world champion is the unbeaten Russian Dmitry Bivol. This is the first time Pascal defends his interim championship.
