The 30-year-old royal was taking part in the second day of the glamorous Audi Polo Challenge in aid of Centre Point, Child Bereavement UK and WellChild at Coworth Park in London.

The fourth-in-line to the throne appeared to be struggling with a bad back and was attended to by a physiotherapist on the pitch before doing a number of vigorous stretching exercises and remounting his horse.

Fortunately the Prince was quick to recover and was later spotted rubbing shoulders with a host of A-list guests including 'Thor' star Chris Hemsworth, actor Tom Hardy, Samuel L. Jackson and singer Sophie Ellis Bextor, reports the Daily Express newspaper.

The 'Devil Wears Prada' actress Emily Blunt was also spotted at the side of the pitch with her husband John Krasinski supporting Harry and his brother Prince William, 32, who was also participating in the match.
