Breaking - Isaac Makwala will run an individual time trial tonight in a bid to get into the 200m semi finals— Natalie Pirks (@Natpirks) August 9, 2017
Details on the trial are still being finalized, including whether or not Makwala will bump any of the already-qualified athletes out if he advances. If confirmed this will give Makwala one last chance at taking down 400m world record holder Wayde van Niekerk at a distance that arguably favors Makwala.
Update: The IAAF has published an article clarifying details of the time trial, including the fact that it will be contested at 6:40 PM London time tonight, before any of the track events start, and it will take place in his originally designated lane, number seven. The article also clarified that no athletes will be bumped out of the semifinals.
