Canada's Dunfee stripped of bronze after battle of appeals

Canadian race walker Evan Dunfee's roller coaster day just took another turn.

Dunfee finished just off the podium in fourth place after Friday's grueling 50 km race, but protested that he was bumped off his stride by Japanese race walker Hirooki Arai, who went on to finish third.

Dunfee won his appeal, and was awarded bronze.

Arai then filed a counter-appeal and was re-awarded bronze later Friday, several hours after the end of the race.
