One week after Patrick Willis’ sudden retirement, 49ers linebacker Chris Borland has informed the 49ers he is also ending his football career due to the long-term effects of repetitive head injuries.
Borland, 24, who made the NFL All-Rookie team, after leading the 49ers in tackles while making just eight starts in place of Willis, told "Outside the Lines" on Monday that he notified the 49ers of his decision on Friday.
The 49ers were not immediately available for comment on Monday night.
Borland said he made his decision after speaking with family members, concussion researchers, friends and current and former teammates, according to the report from Mark Fainaru-Wada and Steve Fainaru, which was posted on ESPN.com. Borland said he also studied what is known about the relationship between football and neurodegenerative disease.
"While unexpected, we certainly respect Chris’ decision,” 49ers general manager Trent Baalke said on Borland’s retirement.— Matt Maiocco (@MaioccoCSN) March 17, 2015
