Dix, Gatlin out of 200 for London
Walter Dix, third in the 100 and 200 metres at the 208 Olympics and second in both events at last year's world championships, will not run in either event at the London Olympics.
The American sprinter scratched from his qualifying heat on Friday in the 200 metres at the US Olympic Track and Field Trials after having suffered a left leg injury in last Saturday's semifinals of the 100.
With his left leg bandaged, Dix was last in last Sunday's 100 final in 10.95. His pull out in the 200 means he will miss both sprints at the London Olympics, although he could yet be selected to a US relay pool for the Games.
Also out of the 200 is Justin Gatlin, the 2004 Olympic 100m champion who won the 100m final at the US trials last Sunday. Gatlin scratched from the event after securing his London berth in the 100.
Wallace Spearmon, who was disqualified from a bronze medal spot at the 2008 Olympics for a late-race lane violation, had the fastest qualifying time in the 200 at 20.17 seconds.
Shawn Crawford, the 2004 Olympic champion and 2008 Olympic runner-up in the 200, was fourth-fastest overall at 20.32.
