Australian team captain Lleyton Hewitt revealed that Nick Kyrgios is in a race to recover ahead of their Davis Cup clash on the weekend.
The Australian team is hosting the USA in Kooyong from Friday to Sunday and could be without Kyrgios, who is recovering from a back injury and illness.
As a result, the 20-year-old has not travelled with the team to training, but Hewitt is confident he will be ready come Friday.
“At the moment he’s taking it easy and trying to get over it 100 per cent,” Hewitt told ABC News.
“I didn’t want him around the boys if he’s a bit infectious. It’s a precaution more than anything. The back and hip don’t seem to be a problem which is very good news.
“He’s played a lot of matches and both he and Bernie [Tomic] are confident coming in with their ball-striking. Come match day I’m backing both those boys.”
Australia face a tough task as Team USA have a strong team that includes the big-serving John Isner, world number 24 Jack Sock and men’s doubles supremo’s Mike and Bob Bryan.
Nonetheless, captain Jim Courier believes the home team will always be the favourites.
“It doesn’t matter one bit, we’re the away team, and we travelled to get here so that’s certainly a factor for them,” added Courier.
“The crowd will be behind them.”
