Olympians have heated exchange after 4-man pileup in 5,000-meter heat: "He took me out"

Pushing and shoving in one race on the track. A cameraman walking into the action in another. Leg cramps and untimely misses in the field.

The often-routine qualifying rounds at Olympic track and field took some strange turns Wednesday with a four-man pileup in one men's 5,000-meter heat, a cameraman who walked into the other and drama in the high jump that left the defending co-champions in dire straits.

The biggest crash came in the first of two men's 5,000 heats when Britain's George Mills and France's Hugo Hay traded elbows, triggering a pileup involving Mills and three others who came crashing down like dominoes.
