New York Cleveland Cavaliers point guard Kyrie Irving would make a decision shortly about whether he would opt to play for Australia at the Olympics.

Irving, who was born in Australia while his father was playing in Melbourne, holds dual US and Australian citizenship. He has justified his choice as number one overall pick in the 2011 NBA Draft with a sparkling rookie season.

Australia has made no secret of their interest in the 19-year-old, who is averaging 18.3 points and 5.1 assists per game after leaving Duke University for the NBA, and Irving has expressed interest in playing in the London Games.

"I'm not sure, it's still up in the air. I haven't made a decision yet," he said. "You'll probably hear about it in the next week or so what decision I make."

Irving would face a technical hurdle to joining the Australians since he represented the US at the under-18 level last year and would have to appeal to the International Basketball Federation (Fiba) to switch his eligibility.

Coupled with that is the fact the US Olympic team head coach is Duke University's Mike Krzyzewski.

Irving said Krzyzewski encouraged him to play for the US Select team, which serves as a feeder programme for the Olympic squad and could pave the way for him to make the US team for the 2016 Games in Rio.
