Sprint legend Bolt is expected to retire after the World Championships in August and continued his preparations by winning in a time of 10.06 seconds in Ostrava on Wednesday.
Speaking after the race, Bolt said: "I'm not happy with the time but I'm just getting into my running, I have some training to do, work on my execution but I'll be fine.
"I'm going to get checked out by my doctor, my coach will give me some training to do and I should be fine, so I've got no worries."
