Apparently they got in a little bit of a scrap today. They both live in Buffalo, and are both from Buffalo, and have been teammates before. I've heard before that these two have never liked each other.
I guess Kane was running his mouth and telling Kaleta he was a winner, and all Kaleta does is lose. So Kaleta kicked his ass right there.
I personally am very happy this happened. Kane has done stuff like this for a while now and is just a dick, so I'm glad Kaleta gave it to him.
