It was over in an instant - not with the snap of a finger, but that of a fibula. Washington Redskins running back Chris Thompson opened a lane for quarterback Kirk Cousins, with Saints defensive tackle Sheldon Rankins in pursuit. A lunge, as Rankins tried to bring Cousins down. A step, as Thompson tried to block him. And a snap, as Rankins' 287 pounds broke Thompson's leg.The injury ended Thompson's 2017 season.
