Baltimore Ravens offensive lineman John Urschel retired from the NFL on Thursday at the age of 26.
A source explained that the results of a recent chronic traumatic encephalopathy (CTE) study, which found symptoms of CTE in 99% of the NFL players brains studied, played a significant role in Urschel’s retirement.
Urschel is pursuing his doctorate in mathematics at the Massachusetts Institute of Technology, where he is a straight A student.
Urschel is a mathematician, and he said the head trauma after a 2015 concussion impacted his ability to think, according to Hensley: “I think it hurt my ability to think well mathematically. It took me about three weeks before I was football-ready. It took me a little bit longer before my high-level visualizations ability came back.” Read more at Bleacher Report.
