But in a surprise move, the 46-year-old was spotted at a training camp practice session wearing Chiefs gear.
He was seen walking alongside defensive coordinator Steve Spagnuolo, who was once his coach at the New York Giants.
Under the experienced coach’s guidance, Pierce won the Super Bowl in 2007 by beating the New England Patriots.
There has been no official announcement over whether he is now joining Andy Reid‘s coaching team or whether he is just a guest defensive advisor.
But Spagnuolo is delighted to have his former star man with him at the Chiefs camp in Missouri.
Spagnuolo said: “I think you guys probably know this. Antonio and I have been close for a long time.
“In ’07 when I went to New York with the Giants, he was the linebacker.
“The present-day version of Antonio Pierce is (the Chiefs’) Nick Bolton now.
“He became a coach, and all the way to being a head coach, he obviously had that when he was a player.
“That’s a nice thing to have when you’re a defensive coordinator, a guy that’s that cerebral.
“I’ve got a lot of respect for Antonio. I’m glad he came through.”
Opening up on Pierce’s current role, Spagnuolo revealed: “The guys are loving having him.
