Olympic swimming: Michael Phelps through after scare

Michael Phelps, the 14-time gold medal winner, comes within 0.07 seconds of being eliminated from the men's 400m individual medley.

Despite winning his heat in four minutes 13.33 seconds, a markedly faster fifth heat leaves Phelps with the eighth fastest time overall.
