Joshua To Have A Re-match With Andy Ruiz In November

A rematch between Anthony Joshua and his conqueror Andy Ruiz Jr will take place in November or December, says Joshua's promoter Eddie Hearn.

American-born Mexican Ruiz produced one of the biggest shocks in heavyweight boxing history to take Joshua's IBF, WBO and WBA world heavyweight titles in New York on Saturday.

A rematch clause was part of the contract for the fight. Hearn said the clause had been triggered on Tuesday after talks.

"After meetings with AJ, Rob Mc[Cracken - Joshua's trainer] and the management team in NY, we have today triggered the contracted rematch clause with Andy Ruiz Jr," Hearn said on Twitter.

"The fight will take place in Nov/Dec at a venue to be confirmed shortly."

British fighter Joshua, 29, was floored four times as Ruiz defied his underdog status to win in seven rounds at Madison Square Garden. The London 2012 Olympic champion subsequently had a concussion test after the first defeat of his 23-fight career.
