This round has been a very cautious one after those round three fireworks.
Round 4
Remember that Klitschko fight? Joshua knocked him down in the fifth and was himself knocked down in the sixth, and then took care of business a few rounds later. Joshua needs something similar to happen again.
Arguably that was the worst round of Joshua's life, that third, and he started by putting his man down on the canvas! He ended it in the deepest of deep trouble.
Round 3
David Haye
Former world heavyweight champion on BBC Radio 5 live
Anthony Joshua is fighting a man who had six weeks notice for this fight, against a man who nobody thought had the firepower. This is insane.
How much has Joshua recovered? He has had 60 seconds. Into the fourth.
This could be one of the biggest shocks ever in boxing. Ever!
Round 3

Anthony Joshua saved by the bell. He is wobbling back to the corner. One of the great rounds in the history of heavyweight boxing.
Anthony Joshua saved by the bell! He was knocked down twice, that coming after he himself had knocked Andy Ruiz down. Three knockdowns in three minutes, once Ruiz, twice Joshua.
This is unbelievable.
Ruiz catches Joshua with a right hand, Joshua tries to hold on, he gets caught again, Joshua is down again. That's twice in 90 seconds!
Ruiz attacks again, Joshua holding on.
Joshua is in trouble again. Legs look gone!
Within a minute of being knocked down, Andy Ruiz knocks Anthony Joshua down!! No-one expected this.

Anthony Joshua is on the most rubbery legs, can he survive?
Joshua up, but having to survive.
Crazy scenes. Both have been knocked down.
A left hook, and Joshua is on the canvas!
First knockdown of Ruiz's career.
Round 2
Carl Frampton
Former world champion on BBC Radio 5 live
That was a better round for Anthony Joshua. Andy Ruiz Jr is a brave fighter and he has a good chin but that was a better round for AJ.
What a venue...
