Australia batsman Nic Maddinson, who missed New South Wales' clash against Victoria last week, will miss the game against Queensland too, starting February 10, because of "personal reasons".

"Cricket Australia and Cricket NSW advises that Australian and NSW batsman Nic Maddinson will not be available for selection due to personal reasons, until further notice," CA and CNSW said in a joint statement.

In the absence of Maddinson, 18-year-old offspinner Arjun Nair, who made his Shield debut against South Australia in Coffs Harbour last year, has been added to the squad for cover.

Maddinson made his Test debut against South Africa in the day-night game in Adelaide, where he fell for a duck. He then made modest scores of 1,4,22, in his next three innings against Pakistan, before being dropped for the third Test against Pakistan at the SCG.

"At the end of the day I've had my chance and I couldn't grab it," Maddinson said last week. "I actually haven't even thought about playing Test cricket again since."

After being left out of the Test squad, Maddinson linked up with Sydney Sixers in the Big Bash League. He scored 75 runs in seven innings.
