 Olympics coming up in less than a week. American sprinter Noah Lyles ran a personal best 9-8-1, winning a 100-meter tune-up in London. USA Basketball has its own Olympic tune-up in London today. They're taking on South Sudan at 3 Eastern on Fox. Kevin Durant questionable to play as he recovers from a calf injury. He only just practiced with the team for the first time on Friday. I'm Nick Cope.
