Just a few months after signing a one-year deal with the New England Patriots, wide receiver Andrew Hawkins has announced his retirement.

The 31-year-old made the announcement via Uninterrupted, saying his body just isn’t responding the way it used to… and he made the decision to call it quits.

“After OTAs and through summer training, my body just didn’t respond and wasn’t feeling the way it should going into camp,” Hawkins said. “Basically it just started breaking down on me.”

He went on to call the decision a “tough call”, while adding that he’s pursuing a Ph.D. in business and economics. During the offseason, he began earning his master’s degree from Columbia with a 4.0 GPA.

Hawkins entered the NFL in 2008, going undrafted. He played six years in the league, playing for the Cincinnati Bengals (2011-2013) and Cleveland Browns (2014-2016). During his career, Hawkins racked up 209 receptions for 2,419 yards and nine touchdowns.

According to ESPN, he has pledged his brain for research into chronic traumatic encephalopathy, or CTE.
