Nigeria's reigning 100 metres champion Tamunosiki Atoribido is out of the team to the 10th IAAF World Championships in Athletics in Helsinki.

The Mobil/NNPC/Nigeria Track & Field defending sprints champion pulled out halfway through his second round heats at the trials with a hamstring injury.

Tamunosiki, who surprisingly won the title last year with a stunning 10.08 seconds, has been plaqued by injuries all season and only managed a 10.40 seconds season's best this year.
