Mexican star Hirving Lozano was shown a straight red card for a swinging arm and PSV were punished with a 2-2 draw against Heerenveen.
PSV had jumped out to a 2-0 lead, with Lozano setting up Santiago Arias for the club's first and playing a part in the second, with his pressure forcing sloppy play out of the back and allowing Luuk de Jong to double the home side's lead before halftime.
But the match would turn just before the break, with the El Tri star sent off and PSV forced to play the rest of the match a man down.
