Australia batsman Chris Lynn has been ruled out of the Twenty20 series against Sri Lanka, replaced by Ben Dunk.
Already in some doubt for the three-match series, Lynn aggravated his neck injury during training.
The 26-year-old is being replaced by Dunk, who was the leading Big Bash League (BBL) run-scorer with 364 at an average of 52.
"It's unfortunate that Chris is not fit to participate in this series, but we are excited at the prospects Ben will bring to the squad," Australia interim national selector Trevor Hohns said.
"Ben was the highest run scorer for the Big Bash in the season just gone, amassing a total of 364 runs in just 222 balls faced and currently sits on an average of 52.
"He has had consistent performances in the BBL, IPL [Indian Premier League] and CPL [Caribbean Premier League] and also brings international experience to the squad."
Dunk has played three T20 internationals previously, scoring 39 runs at an average of 13.
Weakened by the absence of Test players in India, Australia begin the series against Sri Lanka in Melbourne on February 17.
