World Number One, Andy Murray insists he is fit enough to start the defence of his Wimbledon title on Monday.

Murray sparked concerns he might have to withdraw from Wimbledon after cancelling two scheduled exhibition matches this week due to his sore hip.

He was seen limping while practising at Wimbledon over the weekend, but he is convinced he can make it through two weeks of the grass-court Grand Slam.

"I'll be fine to play the event and play seven matches," Murray told reporters at Wimbledon on Sunday.

Murray, a two-time Wimbledon champion, will play the first match on Centre Court on Monday against Kazakhstan's Alexander Bublik.
