A little before 8:30 p.m., the world turned upside down for John Harbaugh and the Giants.
There was 11:20 remaining in the first quarter when Jaxson Dart was down, clutching his left knee following a third-down incompletion for Theo Johnson after Byron Young got him high and Josaiah Stewart hit him low.
Dart limped off on his way to the medical tent. Then he hobbled to the locker room. Then the ESPN cameras showed him getting into a cart to take him for X-rays.
He was questionable to return and never did.
