Northwestern wide receiver Cam Green has decided to step away from football and has announced his retirement from the sport.

Monday night, Green made his announcement via public through Twitter. The receiver cited concussions and head injuries for his decision to retire from football.

Green had one year of eligibility remaining.

“It is with joy and pain that I am announcing my retirement from the sport of football,” Green said. “I am honored to say I played for Northwestern, and privileged to represent this University on such a prestigious stage. Unfortunately, due to concussion and head injuries within my family, I have chosen to step away from the game. Though the love of the game will be everlasting in me, the love for family and health overpowers all.”

Green, a 6-foot-3 receiver from Buffalo Grove, Ill. has played three seasons for Northwestern, totaling 81 receptions for 684 yards and six touchdowns. He had his biggest year in 2018, hauling in 57 catches for 483 yards and four touchdowns.

Green was expected to be one of the top targets in Northwestern’s passing attack again 2019, especially with the departure of top wide receiver Flynn Nagel. But with Green’s retirement means the Wildcats are losing two of their top three pass catchers from a year ago.

The announcement comes before Northwestern begins spring practice. Green is the second Wildcat to retire for medical reasons in the last year, as running back Jeremy Larkin was forced to retire due to a neck condition early in the 2018 season.
