NYON, Switzerland (AP) UEFA suspended top Bulgarian referee Anton Genov while it investigates him for allegedly helping to fix an international friendly in a betting coup.

UEFA said on Tuesday it will not appoint Genov to a European match — an international, Champions League or Europa League fixture — during the investigation.

There were "obvious irregular betting patterns" during a Nov. 14 friendly between Macedonia and Canada, UEFA said.

"After interviewing the referee in question, UEFA has decided not to appoint Anton Genov to any European matches until further notice," UEFA spokesman Rob Faulkner said in a statement.

Genov awarded four penalties, two to each side, during Macedonia's 3-0 victory in Strumica.
