One of the planet's most popular athletes says a back injury will end his season. World 100-and-200 meter record holder Usain Bolt will not run again this year.
American Tyson Gay beat Bolt in Stockholm in the 100 last Friday. The Jamaican was due to compete in the Diamond League's meetings in Zurich and Brussels this month.
A doctor in Munich examined Bolt on Monday, and found a problem with the triple Olympic champion's lower back, which, if not treated, could cause injury to his hamstring or calf muscles.
Jamaican sprinter Usain Bolt said, "I think this season I kind of slacked off a little bit on a lot of things so I can say maybe that's why I got injured this season because I wasn't really deeply focused. My coach, we said that this was going to be my kind of "off" season so I wasn't stressing my exercise that much this season. I have to make sure that, next season, I'm on top of things."
Bolt's been troubled by an Achilles tendon problem this season, but an MRI scan showed that injury was now healed. The 23 year-old's shock defeat in Stockholm was his first in a 100 meter final in more than two years. He was expected to face Gay and former world record holder Asafa Powell over 100 meters at the final Diamond League meeting in Brussels, on the 27th of August.
