COLOGNE, WEST GERMANY, AUG. 16 -- Ben Johnson of Canada won the 100-meter dash at the Cologne Grand Prix track and field meet today in 9.95 seconds, the fastest time in the world this year. It was the second-fastest 100 meters ever.

The world record, 9.03, was set at an altitude of 1,800 meters in Colorado Springs by Calvin Smith of the United States in 1983. Smith was second today in 10.09.

Ten meters after crossing the finish line, Johnson bumped into a photographer and fell. The 25-year-old Canadian star lay sprawled on the track for two minutes before getting to his feet, grimacing and clutching his side.

He walked away from the track without help and did not appear to be seriously injured.

Johnson, after having his back treated with ice, told reporters he was not injured in the tumble.

"It was a shock to suddenly see the photographers there," he said. "I tried to go around them, but was hit on the shoulder and knee. But I'm okay now."

West Germany's Harald Schmid won the 400-meter hurdles in 47.60, edging Calvin Young of the United States.

In the women's competition, Merlene Ottey-Page of Jamaica won the 100 in 10.93. Florence Griffith of the United States was second in 10.96 and Canada's Angella Taylor-Issajenko third in 10.97.
