Fourteen months ago, Akeel Lynch was the starting running back for a Penn State team with high expectations.

Now, he’s calling it a career.

Lynch, who left Penn State for Nevada as a graduate transfer this offseason, announced on Monday that he’s retiring from football after two serious concussions:

Lynch was PSU’s lead back heading into 2015 after posting a team-high 678 rushing yards in 2014. In his three-year PSU career, he had 1,318 rushing yards and seven touchdowns.

He played a lesser role after the emergence of Saquon Barkley, who took the reins of the starting gig in his breakout freshman season.

Lynch was only active in three games this season for Nevada, and he had eight carries for 29 yards. He missed four of his final five games with concussions.

The Toronto native will turn his focus to his masters degree.
