South Africa opener Dean Elgar was on Monday ruled out of the third Test against India as he suffered concussion after being hit by a bouncer from pacer Umesh Yadav, in Ranchi on Monday.
Minutes before the tea break, Elgar tried to duck a short delivery from Yadav, who was in the middle of a hostile spell of short-pitched bowling.
Elgar was hit on the side of the helmet as he took his eyes off the short ball while trying to duck. He immediately fell on the ground and called for medical help, following which the umpires called for early tea.
He was batting on 16 off 29 balls when Umesh bouncer struck him.
Elgar can return to competitive action only after six days said the Cricket South Africa (CSA).
"The opening batsman will be closely monitored over the next 24 hours, followed by reassessment every 24 hours until signs and symptoms resolve. The soonest he can return to play is in six days' time in keeping with the standard concussion management protocol," CSA said in a statement.
Elgar is the third concussion substitute after Marnus Labuschagne of Australia (in place of Steve Smith during Ashes Test at Lord's) and Jermaine Blackwood (vs India replacing Darren Bravo).
Batting at No 8, concussion subsitute de Bruyn was unbeaten on 30 but South Africa were left reeling on 132 for eight in their second innings at stumps on Day 3 after being asked to follow on. They still need another 203 runs to avoid an innings defeat, while India need just two wickets to complete a 3-0 series whitewash.
