And Davies said that Manning failed to answer some of the questions raised by the documentary.
"I have a lot of personal thoughts that really are personal to me", Brady said.
"Their story was not credible to begin with and it's not credible now", Fleischer said in a statement.
Davies' statements on Tuesday struck others as a retreat.
The accusations are in a report by Al Jazeera, based on secret recordings of an unpaid student intern at the facility.
"You don't want to believe your icons can be that kind of guy", said Misha King, a Manning fan.
Davies denied that she was backpedaling.
But Julianne Cartmel, general counsel for the Guyer Institute, told CNNMoney that the employee mixed up some dates. "That's people not understanding it to start with".
"We told Al Jazeera that and they don't seem to be concerned with the truth", Cartmel said.
"He's a big boy", Brady said. That's utterly false, as Al Jazeera has won countless awards for their work in journalism, including the prestigious Peabody Award, and it is generally viewed as a reputable source.
What is going to end up happening is a he said, she said type of battle.
The since-recanted report claimed Manning took human growth hormone as he was recovering from neck surgery. "And it would never be under Peyton's name, always under her name". The documentarians, in turn, insist they carefully laid an allegation at the feet of Mrs. Manning rather than the NFL's all-time leader in yardage through the air and passing touchdowns.
In the documentary, The Dark Side, Sly said: "All the time we would be sending Ashley Manning drugs, like a growth hormone, all the time, everywhere, Florida". The allegations originally made by Al Jazeera focus on Peyton Manning's recovery from injury in 2011.
"Don't reveal your medical condition". On the other hand you have a drug that is actually illegal to prescribe to a patient for anything other than one of three incredibly serious illnesses. However, Sly backtracks in a subsequent statement to Al Jazeera, saying Collins secretly recorded his conversations without his knowledge or consent. In a statement Saturday night, Manning said: "The allegation that I would do something like that is complete garbage and is totally made up".
