If it was judged to be a legal punch by the referee, it will be a stoppage in favour of Wallin. If it's a clash of heads, it will go to the scorecards as they stand now.

The blood is dripping down the side of Fury's face. How much can he see? Four gone. Fury probably has a lead on the judge' scorecards at the moment. But that cut means this one is very much in the balance.

"No panic, no stress," are the calming words from trainer Ben Davison.

Fury keeps pawing at that cut, trying to keep the blood out of his eye. It's clearly causing him problems. Wallin, as you would expect, aims for the cut.

Apparently the referee is saying the cut came from a punch, not a clash of heads. This was not in the script.

Fury is going to have a tougher night than everyone expected.

Can Wallin take advantage of that Fury cut? Fury now has a very visible target on his head.

I think that was from a clash of heads.

For a portion of that third round that blood was streaming down the side of his face. That's a huge gash, the sort that could force a stoppage.

That is a bad cut, right over the right eye of Fury. Looks deep and his corner only have one minute to deal with it.

Fury might want to finish this one quickly before the blood gets too bad and into the eye.

Wallin is trying to force it, and there is a cut over the right eye of Fury. Maybe a head clash has caused that one.

Tyson Fury is trying to fake an attack, cause the Wallin defence to go AWOL and then take advantage. A right finds its way through from the Briton.

You get the impression that Fury very much has not shown his hand just yet.

Really good round from Fury there, some really good meaty jabs. Wallin has to be careful, the more eager he is the more he leaves himself open.

In between the second and third round, we've got the traditional pre-fight singalong of Neil Diamond's Sweet Caroline. A bit late, but there it is anyway.

Fury is backed into the corner and Wallin looks to cause some danger. But he throws a few shots, but nothing too dangerous and the Briton can get himself out of trouble.

Fury, with the Mexican flag colours on both of his gloves, flicks out the jab and is now, like Wallin, is in the southpaw stance.

An even round, hard to split them. Some jabs from Fury and one really good left hand from Wallin.

Fury has been on the defensive for the majority of the opening round, but that should not be interpreted as a strong Wallin round, more a staying out of trouble and seeing how good the opponent is.

No really clean shot landed from either man. Maybe an even round, not much in it.

Wallin does look like he is here to fight though, just as you would expect.

Wallin dives in, aiming for a left to the Fury stomach. Fury said he didn't know much of his opponent and is using these opening couple of minutes to see what Wallin has got.

Wallin, southpaw, tries to get himself into the centre of the ring, looking to dominate, but Fury is trying to work out his distance, popping out the jab early on.

Here we go. A shock on the cards or a step closer to Wilder-Fury II?
