Yes, Nick Chubb retired from the NFL on August 22, 2026, at age 30, ending his eight-season career (from the Nick Chubb page).
He spent seven seasons with the Cleveland Browns and one with the Houston Texans, finishing with 7,349 rushing yards, 1,109 receiving yards, and 59 touchdowns. His career was shaped by two devastating knee injuries — one in college at Georgia (2015) and another in the NFL (2023) — and in his retirement announcement he said "health is the real wealth."
Chubb is also the fourth RB in NFL history to retire with over 1,000 carries and over 5 yards per carry — a testament to his elite efficiency even through the injuries.
