One by one they roll onto the football field, accompanied by a hush, and carry the wounded away.
In Week 8 alone, a Toro Workman in Pittsburgh, a Club Car in Arlington, Tex., and Cushman carts in St. Louis and New Orleans scooped up injured N.F.L. players and whisked them out of sight so that the games could resume.
Injury carts are the overlooked workhorses of the underbelly of football. Already this season, they have shuttled dozens of lame players away, including three Green Bay Packers hauled by a Taylor-Dunn cart in a single half. A line judge with a broken collarbone was carried away by a John Deere in Denver.
