Rain delayed the start of the World Cup match between Pakistan and Sri Lanka in Bristol.
With the square covered and rain still falling, the toss did not take place at the scheduled time of 10:00 BST. Further rain is expected throughout the day.
Both teams have won one and lost one game in the tournament.
Pakistan beat pre-tournament favourites England by 14 runs at Trent Bridge on Monday.
“It’s not looking great, there could be some windows of opportunity for play but we are looking at more wet weather.
“The rain should clear but there is the potential for thundery downpours.”
