Tunisia may have missed out on its first medal at the London Olympics because of bad math. Weightlifter Khalil El-Maoui was in second place of the men's 56-kilogram competition after the snatch but never showed up on the platform for the second lift, the clean and jerk.

Afterward, he blamed his coach for submitting an entry weight that was 10 kilograms too high.

"It was a mistake," El-Maoui says. "I should have started lifting at 148 kilograms but my coach entered 158 kilograms by mistake."
