Saints quarterback Derek Carr injured Monday night against Chiefs

While Carr lamented that he couldn’t be on the field with his teammates to finish the game, he admitted, “I couldn’t do what I needed to do.”

Coach Dennis Allen said he was advised by the medical staff that Carr had an injury to his left side and would not be able to continue.

Carr dealt with several injuries last season, his first with the Saints, but managed to start all 17 regular-season games despite not being able to finish against Green Bay and Minnesota. Against the Packers, he sprained the AC joint in his right (throwing) shoulder and against the Vikings, he suffered a concussion and right shoulder injury.

“I asked if there was anything you could do about it,” Carr said of the oblique. “They said there’s not enough time to do that.”

Carr said it wasn’t a hit that caused the injury; rather, when he torqued to make the throw.

“I just don’ know yet,” said Carr, who threw for his 250th career touchdown and passed the 40,000-yard mark Monday night. “It wasn’t like it was a pain thing. If you can deal with the pain, then you can go. I just can’t do what I want to do. Obviously, it’s fresh, it just happened, but you know I’m going to do everything I can to make sure I’m there.”
