Practice One of the Monaco Grand Prix had to be red flagged after a loose drain cover flew into Jenson Buttons McLaren, badly damaging the car. The session, which Lewis Hamilton dominated, was minutes from its conclusion when Nico Rosberg dislodged the cover just after Sainte Devote, catapulting the piece backwards.It shattered as it took a chunk out the front right side of Buttons MP4-31, while Rosberg also suffered a back left puncture in his Mercedes. It went through the front-wing, suspension and brake intake, reported Button to Sky Sports News HQ. It was an incident that we definitely dont want to see again.
