Boxing's No.1 fighter Saul "Canelo" Alvarez sent Billy Joe Saunders to hospital with a suspected broken orbital bone Saturday in front of 73,126 fans at the AT&T Stadium in Texas.

The super middleweight world title unification bout was scheduled to last 12 rounds but ended after eight as an Alvarez uppercut appeared to cause considerable damage to the Briton's eye.

Returning to his stool between rounds, boxing trainer Mark Tibbs inspected Saunders and did not want him to continue fighting with compromised vision.

Alvarez had done it again. This time, he added the WBO championship to the WBC and WBA titles he holds at the 168-pound weight limit.

The Mexican boxer has not lost since a 2013 defeat via decision to Floyd Mayweather, and has improved year-on-year since then to seemingly become unstoppable across multiple divisions - middleweight to light heavyweight.

Saunders was the more active fighter for while the fight lasted, throwing - and landing - more punches in rounds five, six, and seven, according to Compubox data sent to Insider.

But once the bout had been won, Alvarez was ahead on all three of the judges' scorecards (78-74 x 2 and 77-75).

Alvarez had the edge because of a considerable difference in power. He was more aggressive, loaded up on his power punches, and out-landed Saunders when it came to significant shots.

He landed 58 (38 to the body) of his 110 power punches in the eight rounds compared to Saunders' 30 from 116.

That bodywork, and a particularly brutal uppercut, spelled the end for Saunders.

Watch the uppercut right here:

"The truth is, I knew it. I think I broke his cheek, and I knew he wasn't gonna come out [between rounds]," Alvarez said in his post-fight interview on the DAZN broadcast.

"[When I got] to the corner, I told Eddy [Reynoso, trainer], 'He's not coming out. He's not coming out to fight because broke his cheek.' And that was it."

With victory, Alvarez advanced his pro boxing record to 56 wins (38 knockouts) against one loss and two draws.

It is likely he will now pursue an undisputed super middleweight world championship boxing match against the division's only other title holder, Caleb Plant.

A September date for this bout has been mooted.
