Blocking shots can be one of the toughest and most painful things a hockey player can do. Andrew MacDonald learned that the hard way. While on a penalty kill, MacDonald stood in front of a Mark Letestu slap shot and took it off the knee. Hobbling on one leg, he was able to stay in the play and help clear the puck. It played a key role in the Philadelphia Flyers 2-1 victory over the Edmonton Oilers on Saturday.
