The Colorado Rapids’ MLS home game against Montreal Impact will go on as scheduled on Saturday, but the post-game fireworks display has been cancelled for a rather unusual reason.In a news release issued on Friday, the Rapids explained the decision as being down to “the confirmed presence of plague-infested fleas affecting prairie dog colonies” in the area surrounding Dick’s Sporting Goods Park.The Plague, known as the bubonic plague, killed an estimated 50 million people in the Middle Ages.

According to the Rapids, the health department feels that these precautions “will greatly minimise the risk of exposure to patrons, players, and employees and help ensure a safe experience”.Colorado will look to put the plague to one side as they focus on the matter at hand – turning around their woeful recent form.They are without a win since the end of June and have lost their last two games, against New York City and San Jose.Montreal, meanwhile, are coming off the back of a convincing 4-0 win against Philadelphia as Lassi Lappalainen and Orji Okwonwko each bagged a brace.
