Johnson survives trial scare

Athens gold medal favourite Allen Johnson just scraped into the USA team at the Olympic Trials in Sacramento.

The Atlanta 1996 gold medallist and four-time world champion, who is the world number one this year with a time of 13.05 seconds, had cruised through his qualifying heats but struggled in the final to keep pace with Terrence Trammell and Duane Ross after hitting an early hurdle.
