Colombo, February 11 Australian captain Mitchell Marsh was forced to miss the team's opening match of the ICC Men's T20 World Cup against Ireland on Wednesday after sustaining a groin injury during training earlier in the week.
Travis Head will lead the side in Marsh's absence against Ireland.
"Mitchell Marsh will miss the opening match of the ICC Men’s T20 World Cup after sustaining a direct blow to the groin during training earlier this week. He is experiencing ongoing pain and discomfort which is restricting his movement," a Cricket Australia statement said.
The injury has caused internal testicular bleeding.
"Scans have confirmed internal testicular bleeding, and he will require a period of rest and rehabilitation. His return to play will be guided by symptom resolution and medical advice," it further stated.
Standby player Steve Smith, who hasn't played a T20I since February last year but has been in good form in the format, will travel to Sri Lanka as cover to acclimatize and prepare, should he be required.
