The United States' Trell Kimmons has been choosen to replace Mike Rodgers in the 100m ahead of the Daegu World Championships.

Rodgers, on Friday, voluntarily withdrew from the World Championships and accepted a provisional suspension from the US Anti-Doping Agency (USADA), after he tested positive for a stimulant earlier this summer. Kimmons was already part of the 4x100m relay pool. Rodgers' lawyer, David Greifinger, has indicated to USADA that he will continue to investigate the cause and will decide with his client how to proceed.

The American record holder for 10,000m, Chris Solinsky has in the meantime said he will not be able to compete in Daegu due to a hamstring injury. "Yesterday I had to make the hardest decision of my career," Solinsky said through his Twitter feed.

"I strained my hamstring again during a speed session. I tried everything to get it ready to be able to compete at Worlds, but it was not responding fast enough," Solinsky said. He will be replaced by Andrew Bumbalough.
