Veteran offensive lineman and president of the NFL players association JC Tretter announced Thursday his retirement from the league on Twitter.
In the announcement, Tretter referenced a letter he wrote to himself in May 2011, when he was a tight end at Cornell.
“I am proud of what I’ve accomplished and how far I’ve come from that night when I made the pledge to myself,” Tretter wrote. “I feel like if my 31 year-old self could talk to my 20 year-old self, I could earnestly tell him that we did it. We did everything we said we’d do and more.”
