league rules don't state an amount allowed before suspension. However I know he did only have 3 and got suspended after his 3rd. Well I guess he had 4 calls against him. The last was in game 72 and he didn't get suspended because the tally resets for playoffs. You can go count for yourself or trust someone that watched every game he played, up to you.
A few things I just thought of.
Of Shinnimans 5 total calls for embellishment at least 3 of them came versus Spokane, I think 4 actually. Just strange to me. Goes to show how big of a target Nachbaur and the Chiefs have placed on the kid.
On all of the calls against him the refs also sent off the opposing player. why is this even allowed? Send off one or the other.
Lastly, he has came up bloody or actually in pain on all of the calls. The refs are making judgement calls with bad judgement.
