SYDNEY (AP) — Captain Danny Brough is among three players dropped from Scotland's Rugby World Cup squad Sunday for misconduct which is being investigated by the tournament's integrity unit.

Media reports say Brough, Sam Brooks and Johnny Walker were forced to miss Scotland's flight from Christchurch to Cairns on Sunday because they were deemed too drunk to board the plane.

Scotland entered the World Cup ranked fourth behind Australia, New Zealand and England but has had a disastrous tournament, losing 50-4 to Tonga and 74-6 to New Zealand. It can still reach the playoffs if it can beat Samoa in its final pool match but would likely face top-ranked Australia in the quarterfinals.

Keith Hogg, chairman of the Scotland Rugby League, said "we expect everyone involved in Scotland Rugby League to adhere to the highest standards of behavior."
