Former Badger Chris Borland retires due to concerns about head trauma

Borland hasn't had diagnosed concussion since HS

Former University of Wisconsin linebacker Chris Borland says he’s retiring from the NFL after just one season because he’s concerned about the long-term effects of repetitive head trauma.

Borland told ESPN’s “Outside the Lines” he made his decision after consulting with concussion researchers and current and former teammates.

Borland played for the San Francisco 49ers last season and made 107 tackles in 14 games.

More than 70 former NFL players have been diagnosed with progressive neurological disease after they died and many studies have tied the effects of head trauma in football to brain damage.

“I feel largely the same,” Borland told “Outside the Lines. “I’m concerned that if you wait ’til you have symptoms, it’s too late.”

Borland played for the Badgers from 2009 to 2013 and was a first-team All-American his senior year.

He earned a bachelor’s degree in history from UW and says he plans to return to school and pursue a career in sports management.
