After Justin Gatlin slowed down for the second time in a week in a race, there were probably many who doubted that the sprinter could compete in the Doho Athletics Championships at the end of the month. During a gala in Zagreb on Tuesday, the sprinter limped into goal after being in the lead after 65 meters.

But to Reuters, sprint manager Renaldo Nehemiah gives soothing news.

"The tests showed that he still has 100 percent strength in his leg," Nehemiah writes in an email to the news agency.

The reigning 100m world champion is expected to return to training this week to sharpen the shape for the World Cup.

Last Sunday Gatlin won at a gala in Switzerland at 9.97.
