Six-times Olympic champion Usain Bolt has confirmed his withdrawal from upcoming events in Ostrava and Paris as he continues his recovery from a foot injury.

The 27-year-old - world-record holder over 100 and 200 metres - had been expected to make his return to the track in the Czech Republic on 17 June, but announced on Friday that would not be in attendance for that or for the Paris Diamond League meeting on 5 July.

"As reported a few weeks ago, I had to miss some training in late March and early April due to a foot injury," he posted on his personal website.

"Thankfully, my foot is 100% healthy now and I am back in full training.

"Unfortunately, due to the training that I missed, I am behind where I am at normally at this time of year and will not be ready to race in the Ostrava Golden Spike meet or Meeting Areva in Paris."
