Video: Usain Bolt Disqualified from 100m Final at World Championships

Defending world, and Olympic champion Usain Bolt was today disqualified from the 100m final in the World Championships at Daegu.

After completely dominating the field during the heats, Bolt was the unanimous favourite to win the race and defend his title, especially after the pre-championship withdrawal of main rivals Tyson Gay and Asafa Powell.

Thousands of fans and spectators around the globe were denied the opportunity to see Bolt in the final thanks to the new zero tolerance rules on false starts.  It is the first time such a rule has been implemented at a major championships.  British stars Dwain Chambers (100m) and Christine Ohuruogu (400m) both suffered a similar fate and were eliminated from their respective events.

Check out the first slide to see the video of Bolt false starting and being disqualified.

Questions have already been asked about the success of the rule that has so far denied two world and Olympic champions the opportunity to race in their respective finals within two days.  

What do you think about the rule?  Is this a good thing for athletics or should the more traditional second chance rule (where athletes are disqualified after a second false start) remain in place?
