Calcutta/Chennai: Ten South Africa 'A' players have been hospitalised due to "food poisoning", including four on Sunday, after playing their tri-series match against India A, the visiting team management said.

Opener Quinton de Kock, who hit 108 in his side's eight- wicket loss, was rushed to a city hospital after the game, while three others were also hospitalised during the course of the match.

Cricket South Africa (CSA) also issued a press release, saying that currently 10 of their players are in hospital.

"With half of the squad going down ill overnight, South Africa was forced to play an ill-balanced starting XI that had only four frontline bowlers with the likes of Dean Elgar and Khaya Zondo to make up the rest of the overs," the CSA media release said.

"Reeza Hendricks, Zondo and Mthokozisi Shezi were all on the sick list but had to play because there was nobody else available. But all three had to be hospitalised during the course of the match. The same applied to De Kock who was hospitalised after the match," the release said.

South Africa 'A' players Wayne Parnell, Beuran Hendricks, Cody Chetty, Cameron Delport, Mesha Maharaj had been hospitalised first.

De Kock, who top-scored for the visitors on Sunday and fielded till 25 overs, then complained of dehydration. He was taken to the city hospital where others were admitted. Coach Vincent Barnes and media officer Volvo are also on the sick list.

According to official sources, the South Africa A team members had spent couple of hours on Saturday at a mall and had also dined there.

De Kock had to be rushed into action less than 24 hours after arriving in India as six of his teammates were also on the sick bed.

Due to the bizarre turn of events, the fixture of the tri-series has been tweaked. The Africans were supposed to play Australia 'A' on Monday. But the match will now be played between India 'A' and their Australian counterparts as the South African cricketers continue to recover in hospital.

"South Africa 'A' were due to play Australia 'A' tomorrow, but in the circumstances (10 in hospital) this match has been put back to Tuesday," the CSA media release said.

It has been learnt from sources that that South Africa A team management requested India 'A' coach Rahul Dravid for a change in schedule as most of their players were not fit to take the field against Australia 'A' on Monday. Dravid accepted their request.

On Sunday, the plight of the South African side was understandable when India 'A' team's 12th man Mandeep Singh came in to field after De Kock suffered a hamstring pull. Before that South Africa A's video analyst, Hendrikus Coertzen, was seen fielding in place of left-arm seamer Mthokozisi Shezi, who fell ill.

There was another interesting development in the match as the boundary ropes were taken at least 10 yards behind from where they were during the last match between India 'A' and Australia 'A'.

It has been learnt that Aussie batsman Joe Burns's whopping 14 sixes during that match prompted the move.
