Chennai: Australia A batsman Nic Maddinson will return home on Monday night after sustaining a tendon injury to his right index finger.
The injury occurred when Maddinson took an outfield catch during India A's second innings on Saturday.
"Nic's finger will need to be immobilised in a splint for the next few weeks so unfortunately he will not be able to participate in the remaining four-day match of this tour," Australia A physio David Beakley said.
"He will return earlier to Australia so that he can continue his rehabilitation in Sydney and prepare for his upcoming cricket commitments with New South Wales."
No player will replace Maddinson.
Australia A's second and last four-day match against India A starts here on Wednesday.
The squad: Usman Khawaja (captain), Matthew Wade, Sean Abbott, Ashton Agar, Cameron Bancroft, Joe Burns, Andrew Fekete, Callum Ferguson, Peter Handscomb, Travis Head, Stephen O'Keefe, Gurinder Sandhu, Marcus Stoinis.
