Both of them are at the limit, so both will likely be suspended.
Boulton fight, was a borderline instigator. Sim was a clear instigator not called, really sucks to lose him for 2 games.
Sim has 4 not instigated upon fights:
Kingston - Bishop - 3/7
Kingston - Uens - 11/29
Sarnia - Luecke - 10/27
Saginaw - Sima - 10/26
Boulton has 5 not instigated upon fights:
Sudbury - Street - 01/19
Sarnia - Moses - 12/31
Kitchener - Hlcar - 12/15
Barrie - Dubowsky - 10/11
Owen Sound - Smith - 10/09
I do wonder though, if there is a league process for teams to appeal fights, they believe should have been called instigated. Which would make sense, given the suspension threshold and if a team has a legit argument, it would work just like the appeal of any other suspension.
