UEFA have opened disciplinary proceedings against Lyon after home supporters aimed a laser at Manchester United winger Cristiano Ronaldo during their Champions League clash at the Stade Gerland.

Portugal winger Ronaldo was dazzled by the laser before and during the first leg of the last-16 tie on February 20.

UEFA's Control and Disciplinary Committee will examine evidence in preparation for a hearing on March 20.

Lyon earned a 1-1 draw in that game but then lost the second leg 1-0 to be knocked out of the competition.
