Never underestimate Usain Bolt, says Justin Gatlin

Johannesburg: American sprinter Justin Gatlin believes that Usain Bolt, who is currently suffering from a pelvic injury, should never be underestimated, even for the upcoming World Championships in next month.

The Jamaican would be making a comeback at the London Anniversary Games on July 24-25 while Gatlin will participate in Friday's race in Diamond League.

Gatlin, who is on a string of 26 unbeaten run from August 2013, said that the Olympian should not be ruled out, despite any talk about potential injury, Sport24 reported.

The American said that a lot of athletes are questioning if Bolt would be there in Beijing, but everyone is really holding their breaths to see how he'll go in the London race.

He insisted that Bolt was a gamer, a showman and he would definitely rise to the occasion when it was the time to do so.
