The Irish Mixed Martial Arts Association (IMMAA) has been accused of “deliberately dragging their feet” on introducing appropriate governance and safety standards in the sport.

Sports Minister Shane Ross has said any attempt to compel former Olympic Council of Ireland (OCI) president Pat Hickey to appear before an Oireachtas committee could result in a legal challenge.

The Sports Minister says he does not believe the report into alleged ticket touting at the Rio Olympics has been undermined by key players not taking part.
