ZURICH -- FIFA has opened a case against the Romanian football federation after a firecracker was thrown at Poland striker Robert Lewandowski during a World Cup qualifying match.
The firework exploded close to Lewandowski's feet as Poland prepared to defend a second-half corner during a 3-0 win in Bucharest on Nov. 11.
The match was stopped for several minutes, and the Bayern Munich forward returned after treatment to score two late goals.
FIFA says it opened disciplinary proceedings without giving details of the incident at the National Stadium.
Fans from both teams clashed in the Romanian capital around the Group E match, and police used tear gas.
The return match is in Warsaw on June 10. Poland lead the six-team group and Romania are fourth.
