Schwartz announced his retirement Thursday via his personal Twitter account.
Schwartz's decision comes after he sat out the entire 2021 season while recovering from back surgery. The 33-year-old offensive tackle suggested in his post that his back has responded well to rehab, though he's opting to preserve his long-term health by walking away from the sport. A four-time All-Pro selection, Schwartz began his career in 2012 as a second-round pick with the Browns and then joined the Chiefs ahead of the 2016 season before being released following Kansas City's loss to Tampa Bay in Super Bowl LV.
