The stunt is in aid of the Bobby Moore Fund, set up by the late captain's wife
England footballers have 'shown' their insides in a set of photographs to raise awareness of bowel cancer.
Players including Theo Walcott, Rio Ferdinand, Shaun Wright Phillips, Michael Carrick and David James have all taken part in the campaign for The Bobby Moore Fund.
It was set up in memory of the former England captain, who died from the disease in 1993, aged only 51.
Bowel cancer is the second most common cancer in the UK.
It's estimated that 44 people die from it each day.
"Bobby was one of the greatest footballers of all time," Theo Walcott said.
"To die at 51 is too young. It's important to us that we make more people aware of the disease."
The 'There Is Moore To Know' campaign is aiming to raise awareness of the symptoms of bowel cancer - if caught early the disease can often be controlled.
"My England team mates and I were shocked to find out that bowel cancer kills 44 people every day in the UK," said Rio Ferdinand, "especially when over eight out of ten cases can be treated successfully if detected early enough."
