Chris Borland Retires From NFL

Just days after Patrick Willis’ retirement, 49ers MLB Chris Borland has announced he plans to retire. This announcement is a shocker considering Borland is just 24 years old and 2014 was his rookie NFL season. The 49ers had high hopes to replace Patrick Willis’ production with the potential of Borland, but all that is now naught:

BERKELEY, Calif. — San Francisco 49ers linebacker Chris Borland, one of the NFL’s top rookies last season, told “Outside the Lines” on Monday that he is retiring because of concerns about the long-term effects of repetitive head trauma.

Borland, 24, said he notified the 49ers on Friday. He said he made his decision after consulting with family members, concussion researchers, friends and current and former teammates, and studying what is known about the relationship between football and neurodegenerative disease.
