Piers Morgan has shared a first look at his emotional Life Stories episode with Brighton boxer Chris Eubank.

In a short clip released today, the former world-middleweight champion breaks down as he recalls the fight in which his opponent, Michael Watson, received a catastrophic brain injury that left him wheelchair bound.    

Piers asks Chris: "An incredibly difficult moment for you, for Michael, for the sport, for everyone involved.

"What are your memories of that night?"

Chris looks over to Michael in the audience and responds "I can't tell you how sorry I am", before breaking down.

Chris is set to reflect on his infamous 1991 match with Michael during the episode tomorrow night.

Michael was left with a nearly-fatal brain injury after Chris delivered an uppercut in the ring, causing him to fall back and hit the back of his head against the ropes.

Michael's boxing career was cut short after spending 40 days in a coma and having six operations to remove a blood clot.

Speaking about the interview earlier this week, Piers said: "It was the most powerful moment of any Life Stories episode ever.

"We're up to 100 shows in this series but that one, that moment next week, you have these two great warriors who fought and Michael Watson - he nearly died, he was in a coma for 40 days, in a wheelchair for six years.

"Now made an extraordinary comeback.

"It was so touching to see these two great men, who'd fought each other for the world title and then been defined for what happened in the aftermath, sharing that emotion together.

"It was spine-tingling."

What happened with Eubank and Watson?

Watson, 51, was critically injured in a WBO super-middleweight title fight against Eubank Sr in September 1991.

There was no ambulance or doctor at that fight and it was several minutes before Watson received any treatment.

He spent 40 days in a coma and had six brain operations, leaving him with irreparable brain damage and partially paralysed.
