Khawaja survives 'scary' blow during warm-up

Australia suffered an injury scare ahead of the World Cup after opener Usman Khawaja suffered a nasty blow on the helmet while batting against West Indies in a warm-up match here.

Khawaja was struck by a bouncer from Andre Russell in the second over while Australia was chasing 230, forcing the opener to retire hurt.

He looked in discomfort and walked off the field accompanied by Australian team doctor Richard Saw, sending a scare through the Australian World Cup camp.

However, scans on his jaw later cleared him of any serious injury as Australia breathed a sigh of relief.

"It was very scary," said Shaun Marsh, who hit an unbeaten half-century in the victory.

"It copped him on the side of the cheekbone The main thing is he is OK and can bounce back pretty quickly.

"(Khawaja was) a bit shaken, as you are when you get hit on the head. But he is a tough cookie, Uzzy, and he'll be ready to go."
