He may not have yet got the rematch against Floyd Mayweather that he craves, but Manny Pacquiao was back in the ring on Saturday night.

The 40-year-old, fighting the 70th fight of his career, outclassed Adrien Broner in Las Vegas to retain his WBA world welterweight title.

Pacquiao rolled back the years to see off Broner in convincing fashion despite not getting the knockout in front of the MGM Grand audience.

Two judges gave scores of 116-112, while the third had the score at 117-111 - all for 'Pac-Man'.

Despite his comfortable victory by points, Pacquiao's eye was caught by Broner's glove, causing him a nasty injury, and he has updated fans on his condition, after some reports were surfacing saying he could retire.

"It's okay, it's just what my eyes are watering. It's a scratch to my eyeball ... I've been through this with the right [eye]. Now it's on the left," Pacquiao said to GMA, as per Boxing Scene.

"There's no clutter, it's really a scratch, it's just a bit of a medicine [needed]... It's okay, God is good, we just have to rest, it's easy to heal the scratch in the eyeball."

Pacquiao said he also had a minor injury on his right eye when training for his fight with Jeff Horn in July of 2017. Pacquiao lost the bout by way of a controversial 12-round unanimous decision.

Having seen off Broner with ease and Freddie Roach back in his ranks, Pacquiao is now eyeing up his next fight, though it may not be the one that he wants.

Pacquiao took on Mayweather in the 'Fight of the Century' in 2015, with the American coming out on top, and Pacquiao has called his long-term rival out a few times since, in the hope of a rematch.

"Tell him to come back to the ring and the we can fight," Pacquiao told Showtime.

"I am willing to fight Floyd Mayweather again - if he is ready to come back to boxing.

Mayweather was ringside for the fight and refused to be drawn over a possible rematch.

Showtime's Jim Gray asked Mayweather to "shake or nod" his head in response, but the 41-year-old didn't do either and Mayweather Promotions' Leonard Ellerbe went one step further at the post-fight press conference.

"He's (Mayweather) retired, he has no interest in doing that," said Ellerbe, when asked about fighting Pacquiao again.

"It's not always about the money, believe it or not. What more can the man do?

 We may not get the rematch we get then, but we do know that Mayweather likes his high-profile comebacks.
