Franzen, who missed the majority of the 2014-15 campaign and only lasted two games this season, explained that his concussion symptoms resurface whenever he attempts to exert himself. Khan suggested that Franzen's situation mirrors that of Marc Savard and Chris Pronger, former stars still possessing NHL contracts without much of a chance to ever play again due to the their respective concussions. As sad as it is to see a career derailed by injury, one can marvel at Franzen's past accomplishments with Detroit. The "Mule" collected 370 points (187 goals, 183 assists) in 602 career games, adding power-play tallies in nearly 20 percent of his appearances. In 2008, Franzen scored 13 goals in 16 playoff games and helped Detroit earn its 11th Stanley Cup.
