The incident happened as the former world number one chased down a shot from Belarusian opponent Aliaksandra Sasnovich during her 6-3, 6-4 victory on the Grandstand court.

As the Dane went into her backswing, her braided hair became tangled in the racquet.

"It used to happen when I didn't braid my hair. That's why I started braiding it. Once it gets to a certain length sometimes it can get stuck in the arm or the racquet. It's a first, you know, when it's braided that it's been stuck that good in my racquet," said the 2009 finalist.

"I still tried to hit the ball. Almost took my head off."
