In a notable development for the Canadian Premier League (CPL), Alejandro Diaz scored the first goal validated under the experimental 'daylight' offside rule during a match against Halifax Wanderers on Saturday, October 18. The match ended in a 2-2 draw. This new interpretation of the offside rule allows a goal to stand if there is a full gap, referred to as 'daylight', between the attacker and the second-last opposing player, which diverges from the standard offside rule. The CPL is testing this rule in collaboration with FIFA to minimize marginal offside calls and encourage more attacking football. The concept, championed by former Arsenal manager Arsène Wenger, is being assessed as a potential change to the offside rule. Critics, however, argue that the 'daylight' rule may disproportionately favor attacking teams. The CPL, which does not utilize video assistant referee (VAR) technology, is the first top-tier league to adopt this trial after previous tests in lower divisions in Italy and youth competitions in the Netherlands. The results of this trial will be submitted to IFAB at the end of the year, with the possibility of a global rule change for the 2027/28 European season if deemed successful.
