Colts QB leaves game and returns

Richardson returned for the next trip.

Richardson dodged a charge, climbed back to the battle line and tapped his helmet.

Backup Joe Flacco came into the game for a snap, handed the ball to Jonathan Taylor for a 5-yard gain and Matt Gay kicked a 37-yard field goal.

CBS later reported that Richardson left the game because he was “a little shaken” and “a little out of breath” after the scuffle, but there was no injury. No injuries were reported by the Colts for Richardson.

The Colts' starting quarterback left the field, knelt on the sideline for third down, then went to the bench with the rest of the offense. Apparently he was never examined by trainers.
