Giants quarterback Jaxson Dart faces possible season-ending knee surgery after Rams collision

Injury severity exceeds initial reports

Tests indicate the damage to Dart's left knee is worse than the initially reported sprained medial collateral ligament. Sources tell NFL Network that the second-year star is facing the possibility of surgery to repair the injury. The Giants lost on their seventh snap when Byron Young hit Dart from the right side.

Coach evaluates recovery timeline

Head coach John Harbaugh stated that evaluations on the quarterback's knee are still ongoing as of Tuesday. He declined to comment further on a specific return date while expressing confidence in backup Jameis Winston. The team will announce their direction once they know what medical treatment is required.

Backup steps into lineup

Jameis Winston entered the game after Dart exited but struggled to generate offense for New York. The Giants scored all of their points from field goals during the 28-6 defeat. Winston threw an end-zone interception while Dart watched the second half in a track suit.
