In previous papers, it has been proposed that home teams have advantages over visiting teams in sporting events. Courneya & Carron (1992) demonstrated that learning factors, travel factors, rule fac-tors and crowd factors are determinants of home advantage. Although things such asattendance of spectators or spectator density applied to measures of spectator factors, few studies have focused on the effect of spectators’ absence, because it is common in sports that spectators watch games. To suggest whether spectator factors are determinants of home advantage, this study examined trends in home ad-vantage in the professional football leagues of Mexico. Some Mexican football matches in the 2008-09 season had to take place behind closed doors because of influenza. The results of players’ performance showed a significant home advantage; on the other hand, judgments of referees showed some significant differences in the number of cards due to the presence or absence of spectators.
