Former Penn State defensive lineman Jack Crawford announced his retirement from the NFL Tuesday morning.

“I know my time has come to step away from the game and close the chapter of my life in the League,” Crawford wrote on social media. ”At 16 years old I left my family and friends in the UK and moved to the US. I couldn’t have imagined the journey that lay ahead of me, it feels like it flew by and I’m grateful for every minute.”

Crawford played 10 seasons in the NFL. After being selected by the Oakland Raiders in the fifth round of the 2012 NFL Draft, he recorded 17 tackles over two seasons. In the 2014 offseason, Crawford was waived.

Over the next eight seasons, the Nittany Lion went on to have stints with the Dallas Cowboys, Atlanta Falcons, Tennessee Titans, and Arizona Cardinals. He battled his way into becoming an occasional starter, totaling 146 tackles, 18 sacks, and an interception through 90 games.

At Penn State, Crawford played four seasons, including the 2011 season, affected by the Jerry Sandusky scandal.

In his true freshman year, Crawford appeared in every game. Crawford spent time on both sides of the ball, at defensive end and tight end, recording four tackles.

After breaking into the top of the depth chart in his sophomore year, he became a major contributor for the Nittany Lions. In three seasons, Crawford amassed 85 tackles (including 26.5 for a loss), 16 sacks, and nine pass defenses in Happy Valley.
