What happened to Caulley. He seemed to be gone in the second half. Did he get injured?

Trey Smith seemed to be in the game at running back for most of the second half...No one else noticed?

Perhaps some showcasing going on yesterday?
I'm certain there will be some heavy trade activity in the CFL over the next week or so.
You can count on Coach Matthews making some staffing changes in his doghouse. Also, some of the more stable teams will be tweaking for the 2'nd half.
