Heavyweight world champion Andy Ruiz Jnr has vowed to end Anthony Joshua's boxing career, after confirming their rematch will be staged in Saudi Arabia.
The 29-year-old - who was born in America, but fights for Mexico - shocked the division in June, when he inflicted a first defeat on Joshua to win the WBA, IBF, WBO and IBO world titles in New York.
Ruiz is set to face the Briton again on December 8 in Diriyah - a fight announced by Joshua's camp earlier this month, but not confirmed by Ruiz until now.
On Saturday, the champion posted on social media: "I'm excited to announce my rematch with Anthony Joshua.
"In the first fight, I made history and became the first ever Mexican/American heavyweight champion of the world.
"I am grateful to Saudi Arabia for inviting me. I took it to AJ in The Big Apple and I'm looking forward to ending his career in the Desert."
