KANSAS CITY, Mo. (AP) — New Orleans Saints quarterback Derek Carr suffered an oblique injury in the fourth quarter of Monday’s 26-13 loss to the Kansas City Chiefs.

“It’s a left side, that’s all I know,” Saints coach Dennis Allen said. “The game continues, the coach told me that he has an injury on his left side and is out.”

Allen did not say whether Carr’s injury would require further testing.

Carr left the field with 9:32 to play after throwing an incomplete pass to wide receiver Mason Tipton on fourth down. He appeared to be clutching his waist as the attacker left the field, walked to the injury tent to be examined and then walked to the locker room with the team’s medical staff.

This is the fourth game Carr has left with an injury in his two seasons in New Orleans. He sprained the AC joint in his shoulder against the Green Bay Packers in Week 3 of last season and was concussed twice last year in losses to the Minnesota Vikings and Detroit Lions.

Carr was diagnosed with a left groin injury in Week 4 this season.
