Indianapolis Colts' Chuck Pagano: 'Andrew Luck is running too much'

Indianapolis Colts head coach Chuck Pagano has admitted that he knows quarterback Andrew Luck is risking injury by running with the ball.

Luck ran four times for 20 yards in his side's 27-6 victory over the Cleveland Browns in their pre-season clash.

Pagano told reporters: "He's running way too much, I know that. He's running way too much. We've got to do a better job of keeping him clean."

Indianapolis open their regular season campaign against the Oakland Raiders on September 8.
