Broncos' Sam Brenner: Considering retirement

Brenner (concussion) has cleared concussion protocol but is contemplating retirement, the San Diego Union-Tribune reports.

Analysis:

Brenner spent the entire 2016 season on injured reserve after suffering a head injury last July. He said he's feeling well and has been training as intensely as he normally does in the offseason, but it looks as if he is keeping an open mind to the possibility of ending his career in the name of mental health.
