Eight-time Olympic gold medallist Usain Bolt said he hopes American sprinter Sha'Carri Richardson can "refocus" and get back on the track after she completes a one-month ban following a positive test for cannabis.

“Hopefully she can learn from this and just push on,” Bolt told Reuters when asked about the American’s failed test for the banned substance, which cost her a spot on the U.S. team for the Olympics in Tokyo.
