Novak Djokovic: Star Hurt Signing Autographs

The world's top tennis player Novak Djokovic suffered a bizarre injury scare as he was signing autographs for fans at a tournament in Australia.

The star hurt his leg after a board surrounding the court collapsed as a group of supporters, including children, pushed towards him.

The Serbian left his racquets and bag on the court and limped along the players' tunnel to get a medical assessment in the locker room.

Djokovic was unable to complete a television interview he had agreed to after his 6-3, 6-4 victory over Italian Andreas Seppi in the Hopman Cup.

However he later recovered to take part in a doubles match which was won by Italy 7-6, 6-4.
