Tennis players are used to signing balls and programmes - but one fan had a bit more of an unusual request for Rafael Nadal.

The 31-year-old was doing the autograph rounds after his second-round Wimbledon win over American Donald Young when he was asked to sign something a bit different.

A man handed over his prosthetic leg, complete with a blue trainer on the end.

Wimbledon later tweeted a clip with the caption: "Not your everyday request."

Nadal said it was probably not the "weirdest" thing he had ever had to sign.

When asked if the leg was removed specially for the star to sign, Nadal said: "Was already off. I don't know if he took it off at that moment or not."

It came the day after a man snatched a towel from a boy's hands when American player Jack Sock threw it into the crowd.

Judy Murray said the man should be "ashamed" of himself.

The young fan was later found, with Sock saying he would send him another towel.
