Manchester City's friendly against Houston Dynamo has been cancelled after extreme weather conditions rendered the pitch unplayable.
Texas has been ravaged by thunderstorms and flash floods this week, which caused caused at least 20 deaths in the state and damaged thousands of homes.
Dynamo, who are managed by ex-Burnley and Bolton boss Owen Coyle, had been set to host last season's Premier League champions at the BBVA Compass Stadium in Houston on Thursday as the second of two games in City's post-season tour of North America.
"Tonight's BBVA Compass Dynamo Charities Cup has been cancelled," said a statement on the Dynamo's website.
"Late this afternoon, officials determined that the field did not meet their expectations and therefore have cancelled the match."
Pellegrini said in a City statement: "We are bitterly disappointed for our fans, and for those of Houston Dynamo, that the match has been cancelled.
"We had travelled to Houston from Toronto in anticipation of a great game of football and we recognise many fans have also travelled long distances.
"We thank the entire Houston Dynamo team for their efforts in preparing for the match and regret that the game could not be played."
