At the 2008 Summer Olympics, Bucci ran in the second heat of the men's 400 metres, against seven other athletes, including top favorite Chris Brown of the Bahamas, and Sweden's Johan Wissman. He finished the race in seventh place by two seconds behind Dominican Republic's Arismendy Peguero, with a seasonal best of 48.57 seconds. Bucci, however, failed to advance into the semi-finals, as he placed fifty-third overall, and was ranked farther below three mandatory slots for the next round.
