al jazeera is standing by their reporting even though one of the key figures in the documentary is recanting what he said he was what was captured on tape. nbc s blake mccoy has the story. reporter: football great peyton manning, now threatening to sue over an al jazeera documentary that links manning and several pro athletes to performance enhancing drugs. complete trash, garbage, there s more adjectives i d like to be able to use. but it really makes me sick. reporter: the doping allegations are made in undercover recordings with charlie sly, who claims he interned for a short time at the guyer institute in indianapolis in 2011, at the same time manning received treatment there following an injury. in the documentary, the pharmacist says manning s wife, ashley, was sent human growth hormone, or hgh. everywhere, florida never under peyton s name. it would always be under her name. i have my treatments that i do. she may have hers, that s her business.
that. if it was not true, woman manning have come out and said human growth hormone has never been shipped to my wife in florida. manning has denied taking hgh. manning was on the sideline for monday night football. broncos needing a win over the bengals for the playoff spot. in the fourth quarter, cj anderson for the touchdown to give denver the lead. the game to overtime. broncos up three. a.j. mccarron fumbles the snap. it was 16 degrees at kickoff. the third coldest game in broncos history. we had a steph curry alert last night.
allegations are all refuting the stories. he s getting support from his greatest rival. tom brady telling a boston radio station that nobody has more respect for the broncos quarterback than he does. this morning on today, debra davies, behind the al jazeera report, went out of her way to keep the focus off the future hall of famer. do you have specific evidence that peyton manning himself has ever taken hgh? we have not said that in the program. you re not alleging he took the substance? the only allegation from charlie sly is that growth hormone was sent from the guyer to ashley manning in florida. so it sounds like you don t have evidence against peyton manning? we re not making the allegation against peyton manning. on machine, former bush 43 white house press secretary and current crisis manager ari fleischer joined team manning. fleischer is reviewing the al jazeera reporting to determine
growth hormone all the time, everywhere, florida. it would never be under peyton s name, always under her name. reporter: the five-time mvp says he did receive treatment at the guyer institute in 2011 while recovering from a neck injury but insists he never took banned substances. hgh is banned in the nfl but random testing did not start until 2014. the denver broncos say they support their quarterback 100% and the colts, manning s former team, calls the accusations utterly ridiculous. dr. dale guyer, the clinic s founder, is also dismissing the al-jazeera report, saying mr. sly has fabricated this whole thing for reasons i cannot fathom. posting a video on youtube, charlie sly is now retracting all the statements in question, saying they are all untrue. i am recanting any such statements. reporter: when asked if he would sue al-jazeera, manning told sports writer peter king yeah, i probably will. i m that angry.
some other nfl players as well. prominent players. it seemed the accusations that an athlete had used hgh or any other performance enhancing drug that it was typically baseball. this is the first time we ve seen something like this involving prominent football players. yeah, i think the skepticism with football is a little bit less because it s a gladiator sport, a very hard sport to recover from, and certainly in track, there s more pressure that comes with these allegations. but there have been some of these cases in the past. it s just that when it s peyton manning s name, it s a really big deal. so everybody pays attention, not just those covering the sport, but anybody who knows his name. you can t avoid knowing his name if you re anywhere in america, really worldwide. so it s his name and the allegation. eric, thanks so much for your time this afternoon. we ve got an update on the breaking news in the shooting
