Cricket South Africa have confirmed that Morne Morkel will be out for between seven and 10 days with the ankle sprain he suffered on day three of the first Test against India in Johannesburg.
The fast bowler fell heavily after his right foot got stuck in the turf at The Wanderers as he fielded a ball in the deep.
He will not bowl again in the match and will only bat in South Africa's second innings unless absolutely necessary.
"Morne landed awkwardly on his right ankle while fielding this afternoon. Clinical examination and a subsequent MRI scan confirmed a Grade One ankle sprain," team manager Dr. Mohammed Moosajee confirmed.
"The recovery period is usually seven to 10 days and he is doubtful for the second test starting in Durban in less than a week's time."
South Africa were already beginning to concede a big lead to India at the time and Morkel's absence left a heavy burden on remaining seamers Dale Steyn, Vernon Philander and Jacques Kallis.
India closed the day on 284 for two in their second innings, a lead of 320.
