London Irish head coach Tom Coventry tells BBC Radio Berkshire that he has "never been involved in a game" like his side's 45-14 defeat by Bath.
The first 40 minutes saw Irish scrum-half Brendan McKibbin sent off and two other players were sin-binned.
"You couldn't have scripted it," said Coventry. "I don't think you could come up with a set of events like that."
The 49-year-old was not despondent after the defeat, saying: "For 20 minutes I thought we looked reasonably good."
