Sri Lanka were forced to train indoors at the Wanderers Stadium, after weekend rains had seeped through the covers and made the outdoor practice pitches unusable.
ESPNCricinfo reported that though there was no rain, overcast conditions did little to aid the drying of the surfaces yesterday.
Training of both teams’ will be expected to affect today as well.
The South Africa squad does not officially convene till later today. Groundstaff had provided a centre track for Sri Lanka’s bowlers to train on and will also aim to provide one for South Africa today.
Additionally it is hoped one of the practice pitches will have dried sufficiently to conduct a nets session on.
Sri Lanka were reportedly dismayed at the prospect of training indoors on surfaces they felt may be slower than the outdoor practice pitches, and the Test-match surface.
The final match of the series will get under way in Johannesburg from Thursday.
