Wednesday's result was the Royal Challengers' fourth consecutive defeat in this year's IPL and they remain rooted to the bottom of the points table.
Doull swapped his bowling boots for the microphone after an eight-year international career, and was in the news in January, receiving far less threatening criticism when he was roasted by fans for an on-air comment during the final ODI between New Zealand and Sri Lanka in Nelson.
Doull was commentating during the Black Caps' innings when he appeared to suggest climate change doesn't exist.
"If you listen to the people that believe in that climate change rubbish, then it'll be sunny again," he said.
"They'll be complaining about the heat.
"[We've] had two cracking summers the last two years in England. Heat waves.
"That was in the middle of a dry summer," he said, raving about high-scoring matches at last year's Royal London Cup.
Doull, who played 32 tests and 42 ODIs for New Zealand, was predictably slammed on Twitter.
