The Dallas Cowboys and New York Giants have a pair of indispensable players, and each team saw one return to the locker room with an injury late in Thursday night’s game that the Cowboys held on to win 20-15.

Cowboys edge rusher Micah Parsons was first. He was helped off the field late in the fourth quarter. He went to the medical tent, then came out with his left shoe and sock off, got on a cart and was taken to the locker room.

Giants rookie receiver Malik Nabers was next. Right after Parsons got hurt, the Giants went for it on fourth down and Nabers couldn’t hold on to the catch. He remained on the sidelines for a while while athletic trainers tended to him. Shortly afterwards he was back in the dressing room. The Giants ruled him out due to a concussion.

Parsons is one of the best defensive players in the NFL and the Cowboys can’t afford to be without him for long.

Nabers is a rookie, but is already a star. He had 12 catches for 115 yards Thursday night before being injured and is the Giants’ best offensive player just four games into his career.

Every team will be concerned about the status of their injured stars in the coming days.
