South African Lungi Ngidi was rushed out of the stadium in an ambulance after the fast bowler hit his head while attempting a catch in Saturday's Indian Premier League game between Delhi Capitals and Punjab Kings.
The Delhi bowler was back-pedalling but misjudged the catch, falling backwards and hitting his head on the turf.
The match was stopped for 15 minutes as an ambulance was called to take the 30-year-old off the ground.
Sri Lankan Dushmantha Chameera came on as a concussion substitute before the match resumed.
