Steven Gardiner, 21, of the Bahamas was a clear second in 44.41 and 20-year-old world junior champion Abdalelah Haroun of Qatar blasted through at the end to snatch bronze in 44.48. Makwala, third-fastest in the year this season, was scratched from the race earlier on Tuesday having also been withdrawn from Monday's 200m heats after vomiting before he got on to the track.

In his absence, Van Nierkerk looked an even shorter-odds favourite and duly delivered, barely seeming out of breath when he crossed the line with his thoughts already turning to the 200m.
"I’ve got a good team to help me recover and its back to work [Wednesday]," he said. Van Niekerk had huge sympathy for Makwala. "It was definitely a heartbreaking moment," he said.

HE HAS DONE IT!@WaydeDreamer showed his class to win the 400m world title in a time of 43.98s.#IAAFWorlds pic.twitter.com/CQl90elpnI — SuperSport (@SuperSportTV) August 8, 2017"I saw him just before the 200 heat and the only thing I could think of was just wrapping my arms around him and telling him he should get well soon. "As much as we want to win gold medals, we also want to go out there and have best guys on the track with us. It’s such a massive pity. He’s a strong athlete, I’ve seen him break through a lot of challenges. So I have a lot of sympathy for him.
"I wish I could give him my medal to be honest, but this is sport. We need to go out there and fight for our opportunities and it could’ve happened to any one of us. We all have tough times, we just need to get up and fight harder." Long-striding Gardiner, who set a national record 43.89 in the semis, could not quite reproduce that on a cold London night but looks equipped to challenge Van Niekerk in the future.

This is how much it hurts The medallists of the 400m at #IAAFworlds @WaydeDreamer @_SpeedyStevie pic.twitter.com/MWGS9BSDJW — IAAF (@iaaforg) August 8, 2017Haroun, who switched nationality from Sudan to Qatar two years ago, was last with 70m to go but edged past Baboloki Thebe of Botswana (fourth) and Jamaica's Nathon Allen (fifth) in the final metres. Fred Kerley had scraped into the final as a fast loser but finished last as the United States failed to medal in the event for only the second time since the championships began in 1983.
