Usain Bolt revealed he is receiving treatment on a strained hamstring following his win at the Cayman International.
Jamaican clocked a modest 10.02 seconds in the 100m final of the event on Saturday. During his final few paces, one could see a slight grimace on Bolt's face.
Following that, he travelled to Munich to receive treatment from former Bayern Munich team doctor Hans-Wilhelm Muller-Wohlfahrt.
"It wasn't the best but as long as I come out injury free, that's the key thing," Sky Sports quotes the six-time Olympic gold medallist as saying.
"I didn't feel as smooth as I wanted to but as I always say, it's hard to just come into your first race and do extra well.
"I am never worried. I've been in worse situations. It's just race rusty. I can tell. I could feel the difference from when you are flying from when you are not."
