Frank Warren and David Price have both dismissed Andrew Flintoff's foray into boxing before the 34-year-old has even had a fight.
Flintoff, nicknamed "Freddie", will complete his switch from international cricket to boxing on November 30 when he faces an as-yet-undecided opponent at the MEN Arena.
The fight will be shown on BoxNation, but Warren believes that it will be "car-crash television".
"For me it's car crash television, I'll be blunt about it," the promoter said.
"I'm not taking anything away from him, it's being shown on BoxNation which I'm involved in, but I won't be promoting it."
Price, the British and Commonwealth heavyweight champion, echoed Warren's beliefs but is ready to give Flintoff a chance if his motives are genuine.
"Freddie's as entitled as anyone to try it out and some people come to professional boxing later in life," Price said.
"But if it's just some type of PR stunt then it's disrespectful to boxing.
"The reality is he could get hurt if there's someone in front of him who'll stand up and throw punches back. It's car crash TV but will probably get people watching."
Flintoff, who is being trained by former featherweight world champion Barry McGuigan, has already applied for his professional boxing licence.
