It was April 12, 2003 and Serie B was on the home stretch. Catania were 16th, in the thick of a relegation battle, and were hosting a Siena side just two points off the top. The match finished 1-1, which did neither team any favours, but there was a problem. Siena had fielded an ineligible player in defender Luigi Martinelli, who was still serving a ban. What should’ve been a simple overturning of the result morphed into mayhem.
