Having come off the track, all four have been talking to BBC Sport about the incident.
Christian Malcolm: "We are a team. It's unfortunate. It's one of those things that happens but it's a fantastic performance to run the time we did. Daniel has come in at the last moment. This is a big stadium and it can be overwhelming."
Danny Talbot: "I don't know what happened. I just couldn't catch Adam. I'm really gutted and it's devastating."
Adam Gemili: "I went off. Maybe I went early or too hard. It's disappointing as we could have been in contention in the final."
Dwain Chambers: "At the end of the day we are proud to be here representing the country. We have to build as a team and hopefully we can do better in the future."
