Rain delayed the scheduled 10:30am local time (0930GMT) start of the second Champions Trophy semi-final between India and Sri Lanka in Cardiff on Thursday.
Early morning rain cleared to allow umpires Richard Kettleborough and Aleem Dar to carry out an inspection at the scheduled toss time of 10:00am.
Officials then announced the toss would take place at 10.40am, with a view to starting at 11.00am, weather permitting.
At present, there was no reduction from the standard 50 overs per side for a one-day international.
Both sides must bat for a minimum of 20 overs for a result to be declared.
If rain means no result is possible, India will go into Sunday’s final against tournament hosts England at Edgbaston on account of having won Group B, with Sri Lanka runners-up in Group A.
There is provision for a ‘super over’ in the event of a tie, but there is no reserve day.
England beat South Africa by seven wickets at The Oval in Wednesday’s first semi-final.
Thursday’s match is a repeat of the 2011 World Cup final which India won by beating Sri Lanka by six wickets in Mumbai.
Since then the Asian rivals have met in 10 one-day internationals, with India winning seven, Sri Lanka two and one match tied.
