Melbourne: Australian coach Justin Langer on Saturday hinted that their regular opening batsman David Warner could miss the third Test.
Warner was ruled out of the T20I as well first two Test against India due to his injury.
When asked about Warner's injury, Langer said the former Australian vice-captain is still recovering from a groin injury he sustained during limited-overs series against India.
The third Test begins on Jan 7.

"As we've said for the last few weeks, there's no one more professional and he's doing everything possible," Langer told host broadcaster.
"We saw him bat the day before the game. He's batting again (in the nets) this afternoon here at the MCG. So in terms of his batting, he's flying.
"It's just .... he's still having some trouble with his groin, and we know how dynamic he is, his running between the wickets, the way his movement is all the time.
"We still have a few more days until the next Test match. Fingers crossed he's ready to go."
Matthew Wade was promoted as an opener in Warner's absence and young all-rounder Cameron Green included in the middle order.
And so far, Burns and Wade have failed in proving Australia a solid start. The duo scored 16 and 70 in Adelaide and 10 in the first innings at the Melbourne Cricket Ground on the first day of Boxing Day Test.
