Athletics has forever been a sport covered in controversy.
Substantial bans for drug abuse, the curious case of Caster Semenya, and plenty more off-track issues have overshadowed some brilliant athletic moments.
For every Olympic Games, World Championships, and Commonwealth Games, there are issues casting doubt over some big-name athletes, and probably the biggest name covered in controversy is Justin Gatlin.
The American has been banned from athletics on two separate occasions due to drug abuse, and despite calls for him to be banned for life due to his latest suspension, Gatlin is still allowed to compete.
And so, the 35-year-old took to London this weekend to compete in the World Championships, and cue more controversy.
Going into the event, everyone was talking about it being Usain Bolt's final 100m race. His final outing in the sport he's dominated for years.
Olympic golds, World Championship golds, and several world records, Bolt is the GOAT of athletics.
However, it didn't end in a fairytale manner as Bolt finished third in the 100m race, behind Gatlin and Christian Coleman.
Gatlin winning the race was met in expected fashion. Thousands of boos and jeers as the controversial star celebrated his impressive race.
Fast forward 24 hours and the boos were present once more, this time, for the medal ceremony.
Gatlin's name was read out, and the London Stadium greeted him with more boos than jeers, a stark contrast from the reception Bolt got just minutes prior.
It's safe to say, everyone has had an opinion on Gatlin and his win, and another athletics legend has weighed in on the subject.
Michael Johnson, a 13x Olympic and World Championship gold medalist, took to his official Twitter account to sum up how he feels about Gatlin's win and athletics in general.
As you can see, he's not impressed with the whole saga, just like the millions across the world, and it's clearly something that the IAAF are going to have to deal with.
So unfortunately, it wasn't a dream farewell to Bolt, but it was certainly a weekend to remember, but perhaps for all the wrong reasons.
