The Argos new Strength & Conditioning Coach. Article doesn't say why he retired other than having suffered a serious injury.

He had a serious ankle injury last year and hasn't recovered.

Yeah, I also think he had a concussion as well.

Didn't Suber give him one of those injuries? 

I always liked watching Kackert play. Kind of reminded me of Josh Ranek. It's a shame he has to hang up the cleats.

One of the reason's that the Argos traded up to get Coombs.
