Aaron Rodgers was in a joyful mood while talking about the performance of his 2-1 New York Jets during his weekly press conference on Wednesday.
But the mood changed when the topic shifted to the health of Brett Favre, who revealed Tuesday during a congressional hearing that he has been diagnosed with Parkinson's disease.
Rodgers and Favre were teammates with the Green Bay Packers from 2005-2007. While their relationship was rocky early on after the Packers drafted Rodgers to be Favre's successor, they've since developed a close bond.
Rodgers said learning about Favre's Parkinson's diagnosis was "tough" but he also understands brain and neurological disorders can be an unfortunate consequence of playing football.
