Makwala's coach bullshitted on the BBC though saying he had been sick once. The IAAF doctor said he came into the medical room voluntarily and had been being sick since 10pm the previous night (or the last 10 hours can't exactly remember this bit). This is what they told the on-site doctors. They determined this was a virus based on his symptoms.
Ya coach could extend the truth....
I believe that the guy got sick, ....i bet a lot there is no test data ... i believe Mak wanted something for his stomach so he could run the next day, not to get thrown out .... i bet a bit of cash, he had food poisoning ... i bet the farm this would never happen to Mo, Bolt, in one billion years.... i bet a ton that, while some at the IAAF are telling the truth, many others are not, no matter what, the various statements need to be documented and lined up.
this will give a window into the soul of the IAAF, or lack there of.
