Merritt sorry for 'foolish mistakes'

World and Olympic 400 metres champion LaShawn Merritt faces an uncertain future after admitting he made a “foolish, immature and egotistical mistake” in taking banned substances which led to three positive drugs tests.

Merritt last night accepted a provisional suspension after admitting he had used an over-the-counter male enhancement product containing DHEA (dehydroepiandrosterone) and pregnenolone.
