Australia opener David Warner will play no further part in the second Test against India after suffering a concussion when he was struck in the head while batting on Day 1, the team said on Saturday.
The tourists, who suffered a heavy defeat in the opening Test and were dismissed for 263 in their first innings on Friday, will bring Matt Renshaw into the team as a concussion substitute.
Warner faced a bouncer barrage from India seamer Mohammed Siraj and was hit twice - once on his arm and then on his helmet - needing medical assistance.
The left-hander scored 15 before Mohammed Shami dismissed him caught behind to end his struggles after a harrowing day for the left-handed batsman.
