Update: I see from this Scratching Post blog entry that Ellingson was out injured for this practice.
I was at the Moncton game and noticed that Greg Ellingson had no catches in the game. According to the score sheet he had a tackle so he at least played some. I'm not sure if he was covered heavily by the Alouettes or was injured. Hopefully not injured, but a little odd considering Ellingson is amongst the CFL leaders in receiving yards.
