Subban (76) after Jarnkrok scored a goal against the Columbus Blue Jackets during the second period of an NHL hockey game, in Nashville, Tenn. Mike Fisher has announced his retirement, a move that means the defending Stanley Cup finalists must select a new captain. Fisher, 37, said in a letter to Predators fans that "this is the hardest decision that I've ever had to make, but I know I've made the right one." (AP Photo/Mark Humphrey, File)
