The presenter joined cricket star Andrew ‘Freddie’ Flintoff, Jamie Redknapp and Peter Crouch for the charity game of golf.
Piers went on to reveal he had won the tournament, but things took an unlikely turn when he tumbled off his chair.
The TV broadcaster confessed: “At 55, and not exactly size zero, there is a certain unstoppable momentum to such a moment, and I tumbled painfully backwards on to the rough terrain with an almighty crash.
“Flintoff instantly sprang out of his own chair and set off on a wild cackling charge past me screaming ‘YEESSSSSS!!!!!!!’ as if he’d just taken a hat-trick at Lord’s in an Ashes test match.”
