The fourth runner from the right is Dave Sime of Duke at the instant of pulling a groin muscle during the 200-meter dash at the NCAA meet in Berkeley, Calif. last Saturday. As Sime grimaces in pain his oblivious rival in the next lane, Bobby Morrow of Abilene Christian (fifth from right), spurts on to eventual victory—after Sime staggered, slowed and stopped. By a chain of consequences, the injured Sime, who has run the fastest 220 ever, is expected to miss the AAU meet this weekend and thus his last official chance to qualify June 29-30 for an Olympics 200-meter berth. It could also hobble him in the 100-meter trials (see page 46)
