Zhang KOs Wilder in Round 5 in a stunner! Wilder looked lost for most of the fight, then turned his back to Zhang before Zhang landed the huge right hand that floored the former champ.

Down goes Wilder!!

Round 4: A tiny bit better from Wilder, but still not enough to win the round. Zhang staying busier, but that isn't saying much. Slow-paced fight with not much action so far.

Round 3: Zhang is making Wilder very uncomfortable. He hasn't found a home for his right hand and he's getting pummeled by the much bigger Zhang.

Round 2: Zhang may have hurt Wilder and was unloading some shots in the corner that Wilder mostly avoided. Wilder doesn't look at all like the Wilder of old. Zhang is backing him down and taking it to the former champ.

Round 1: A bit of a feeling out round between the two big men. Zhang's 68-pound size advantage is noticeable, but he didn't let his hands go much.

Up next: The heavyweight main event between Zhilei Zhang and Deontay Wilder.

The ref has the ring doctor look at Hrgovic's cuts and the ref calls the bout!

Round 7: Nice round for Dubois. Landed some big shots and is starting to take control. Hrgovic looks gassed and it's wild he is still standing. Saved by the bell perhaps

Round 6: More punches from both sides, but Dubois looks strong.

Did someone outlaw body punches and nobody told us?

Either Dubois has a chin of steel or Hrgovic doesn't punch really hard.

Round 5: Lots of action. Dubois looks like the fresher fighter even though he keeps getting hit.

Update: The ref says the cut was caused by a punch, but no one expects this one to go the distance.

Round 4: Hrgovic keeps landing but a cut from a head-butt earlier in the bout is giving him a little bit of trouble. Still, Hrgovic had a nice round.

Round 3: Pace has slowed a little but defense remains just a mere suggestion. Dubois had a nice round, but Hrgovic got going near the end.

Round 2: Hrgovic keeps landing on Dubois, but Dubois isn't going anywhere.

Round 1: This fight is a banger. Two big boys just hitting each other. Hrgovic landing better early, but little effect on Dubois.

Here we go! Hrgovic-Dubois is on

Next up is the interim IBF heavyweight title fight between Filip Hrgovic and Daniel Dubois. Hrgovic is the -290 favorite in a bout that is not expected to go the distance.

Bivol impressively stops Zinad in Round 6 to defend his WBA light heavyweight world title! Ref waves it off after Bivol lands several uncontested shots!

Next up, is a light heavyweight title fight between Dmitry Bivol (-3000) and late replacement Malik Zinad (+1200). And, Zinad has already hit the canvas.

Sheeraz unloads and the ref waves off the fight and saves Williams from taking any more damage.

Down goes Williams, who is saved by the bell! What a shot from Sheeraz!

Sheeraz has looked great against Williams. "Ammo" came out with some fire at the start of Round 10, but unless he can somehow get a knockdown it's too little too late.

Williams' right is swollen nearly shut and he's still just eating shot after shot from Sheeraz. Sheeraz could likely end the fight if he would just put some combos together.

Williams is continuously getting tagged by Sheeraz, whose size and length is a real problem for the 160 pound division.

Sheeraz's jab is on point vs. Williams. Both fighters have already been hurt early. This fight could be over sooner than later.

Ford was super classy after the win and gave Ball his flowers.

Nick Ball pulls off the upset! Incredible fight and definitely worth a rematch.

What a war! Fight ends after 12 and the scorecards are likely to be all over the place. Tough one to score.
