Djokovic OK after injury scare (From This Is Wiltshire)

Novak Djokovic has been given a fitness scare in the build-up to his Australian Open defence at the Hopman Cup.

The Serbian limped away from court following his singles win over Andreas Seppi, with a railing falling on his leg while he signed autographs for fans.

The 25-year-old recovered sufficiently to partner Ana Ivanovic in the doubles, though, as his country beat Italy 3-1 on day three of the tournament in Perth.

It capped a hectic day for Djokovic, who was a late arrival on the west coast after winning an exhibition event in Abu Dhabi on Sunday.

He still beat Seppi 6-3 6-4, even if he admitted to not being entirely present on court.

"I arrived quite late and didn't get a lot of hours of sleep and I felt like I was dream-walking," he said after the match.

"I broke the ice after the first set and felt a little bit better."

With Ivanovic having already seen off Francesca Schiavone 6-0 6-4, the duo then saw off their counterparts 6-0 6-4.

The Australian Open starts on January 14, with Rafael Nadal, who Djokovic beat in this year's final, having already withdrawn citing illness.
