Wisconsin fanspeltedofficials with snowballs after a controversial 13-7 lo s to Northwestern Saturday.Oh, and their own cheerleaders too.MORE: | Refs mobbed after Wisconsin-Northwestern by snowballs. Sconnie Sports Talk James Washington Jersey (@SconSportsTalk) Wisconsin cheerleaders leaving the field after being pelted with snowballs by their own fans. Je se Temple (@je setemple) Why were Wisconsin fans chucking ice at the refs and their own cheerleaders? They called back three touchdowns that would have given the Badgers the Pittsburgh Steelers Hoodies Sweatshirts lead and,likely, a win.The first touchdown overturned was a fantastic punt return by Alex Erickson, which was called back for "invalid fair catch" when he tried to waveteammatesaway from the bouncing ball. Rashaad Coward Jersey While technically correct per NCAA rules, it seemed evident Ericksonwas not calling for a fair catch.Fair catch? Or worst call of the CFB season? Get it together! Adrian Dedering (@deeds002) The second touchdown called back, with two minutes Diontae Johnson Jersey remaining in the game, wasa 22-yard strike from quarterbackJoel Stave toTroy Fumagelli that was initially ruleda touchdown. After review, it was apparent his Ahkello Witherspoon Jersey knee was down at the one.On that same drive, referees overturned this touchdown because the wide receiver did not complete the catch.Wisconsin was unable to score afterward, and eventually lost, 13-7.Which, of course, led to snowballs being flung at defensele s cheerleaders.
