Usain Bolt will make his return to competition in Friday's London Diamond League meet after withdrawing from the Jamaican national championships due to a hamstring injury.

Bolt traveled to Germany to be treated by Dr. Hans-Wilhelm Muller Wohlfahrt, who has previously treated the Jamaican star before major world championships. Last summer, Bolt struggled with a back injury and then returned to win gold in the 100, 200 and 4x100-meter relay at the world championships in Beijing.

Bolt showed no signs of injury as he practiced in London on Wednesday afternoon and was filmed by the Jamaica Gleaner's Andre Lowe.
