Next up, it’s the co-main event!

Valentina Shevchenko puts her flyweight gold on the line against Lauren Murphy.

Diaz looked sharper than some of us thought he would, but there’s no doubting that he seemed off in certain moments – not least the finish.

Lawler, meanwhile, ends a four-fight losing streak by avenging his 2004 defeat by Diaz.

“I knew I was leaking here,” Diaz says, pointing to his bleeding nose, “so I didn’t want to make too much of a mess.”

You can’t help but feel he’s speaking about something bigger than just a bloody nose...

It’s all over!

Diaz hits the deck slowly after a clean right hook by Lawler, and it’s unclear for a moment whether Lawler will let his opponent back to his feet...

But there’s no option to! Referee Jason Herzog waves it off after Diaz tells him he doesn’t want to continue!

Robbie Lawler def. Nick Diaz via third-round TKO (punch, 0:44).

Lots of sneaky hooks and uppercuts landed for Lawler in the second round, getting around Diaz’s guard.

Third round begins.

It’s one-way traffic in favour of Lawler at the moment. Diaz, remarkably at 38, seems as durable as ever so far.

Both men have landed more than 100 significant strikes each already! No problem with pace.

“You’re killing this guy,” Diaz’s corner tells him.

Lawler appears to hurt him with a digging left hook into the body early in the second round, though.

“Diaz” chants to more good body work from the returning icon.

What an ending to the round, too! The old rivals trade combinations against the fence. Lots of good counters from Diaz.

One round down, four to go...

The pair trade fierce body hooks in close.

Diaz is loosening up and, dare I say it, starting to look pretty sharp...
