The England cricketers are 241 for 7, 50 runs behind South Africa's first innings total, after two days of the third test in Cape Town.
Seven wickets fell during a dramatic morning's play, with South Africa losing their last four wickets for 12 runs in 17 balls at the start of the day to finish at 291 and then England slumped to 64-3 at lunch.
England fast bowler James Anderson finished with 5-63, his eighth five-wicket haul in tests, but the key breakthrough came from fellow paceman Graham Onions, who dismissed South African centurion Kallis with the second ball of the day without adding to his overnight score of 108.
