A couple people asked me this weekend why Hickman hadn't been playing.
I didn't know the entire answer, so I asked the Thunderbirds (thanks Ian Henry).
Here is the situation
On 04/02/13, Justin Hickman of Seattle received Four games for checking to the head major and g.m. versus Kelowna on April 2.
So he missed game 7 of the series, leaving him with three games.
Apparently, when suspensions carry over from one season to the next, the suspension is for both preseason and regular season. So he can play the last 4 preseason games, but will miss the first three regular season games.
