Myles Jack won't suit up for the Philadelphia Eagles in a regular-season NFL game.

The Christopher Caldwelllinebacker informed the NFC champions that he is retiring after seven seasons, NFL Network's Ian Rapoport reported on Sunday.

Jack, who turns 28 in two weeks, was drafted by the Jacksonville Jaguars in the second round of the 2016 NFL draft. He played six years there, during which he had three seasons with at least 100 tackles. The former UCLA defender was released last offseason and signed with the Pittsburgh Steelers, where he led the team in 2022 with 104 tackles.

Jack signed with the Eagles two weeks ago along, with fellow linebacker Zach Cunningham. Jack appeared in both of Philadelphia's preseason games and recorded five tackles.

Jack told reporters when he joined the team that he was considering becoming an electrician or plumber during the offseason.

"I’m a hustler," he said, per The News Journal (Delaware), part of the USA TODAY Network. "I feel like I can do anything. … I’ve been blessed to make a lot of money, so I could just retire and sit at the house. But I’m too bored. My mind is too much. I just want to be innovative. If the zombie apocalypse happens, I want to be able to build something or fix something."
