Finch was struck on the index finger by Mohammed Shami and was forced to retire hurt early in the second innings.

"I think his finger is still numb. We'll have to see how it goes overnight," Mitchell Starc told Fox Sports after the day's play. "There's a bit of swelling there and he will, I am guessing, spend the night with the doctors and test it out in the morning to see if he can keep batting."
"I think that's the third time he's been hit on it in the last four weeks. So not ideal. Unfortunately I was one of those one's that got him. Hopefully it goes okay overnight and he can keep batting tomorrow at some point."
Unfortunately for the Australian opener, this was the same finger he had hurt earlier in nets when he was hit by a quick one from Starc.
After looking out of sorts in the first Test, Finch has found some sort of fluency in his batting. He scored a half-century in the first innings and was looking solid for 25 in his second innings before the blow.
Ricky Ponting, the former Australia captain, said Joe Burns should replace Finch if he's unavailable for the third Test in Melbourne starting December 26.
"I saw Finch a couple of days ago and he had a big, black bandage around his finger then with some extra padding, so it was already a bit tender anyway," Ponting told cricket.com.au.
"But some of the camera angles we saw today it looked like it was badly bruised on the bottom side, maybe split, and the bone might have been coming out.
"We just hope it's not that bad. Joe Burns is the obvious one to come in and open. He's the opener around the country who's scoring the most runs at the moment."
