Zinedine Zidane's charity soccer match Saturday in Vancouver is in danger of being cancelled after the former French star suffered a freak injury.

Organizers said Zidane injured his back while bending down to pick up his child Wednesday night as he was watching Vancouver's Canada Day fireworks display.

The game at B.C. Place is the finale in the three-game "Friends of Zidane" tour that has already staged events in Toronto and Montreal.

The former FIFA World Player of the Year underwent physiotherapy Thursday, but may have pulled a tendon in his back and recovery usually takes a week.

The games pit Zidane and other current and retired international soccer stars against local select sides with proceeds going to UNICEF and other causes.
