Grand Rapids Griffins center Mitch Callahan is getting a good amount of attention on Twitter after posting a selfie during last night’s victory over Iowa.  Callahan took a puck to the mouth in the first period and posted a selfie on Twitter from inside the locker room about 15 minutes after he lost several teeth on the ice. The bloody photo had been retweeted over 45-hundred times within hours. The sports website Deadspin also picked up the story.
