Cronulla’s entire squad has been barred by one of the Sutherland Shire’s most popular nightspots as a result of a late-night incident that the Sharks and police are investigating.

The Herald can reveal Cronulla Sailing Club has taken the extraordinary step of telling the area’s NRL club that their players are no longer welcome there.

The blacklisting comes after an altercation on the night of December 21 in which a series of scuffles are understood to have broken out across the venue involving lower-grade players, prompting police to be called.

The Sharks have been investigating the incident since before Christmas and are yet to determine whether to begin disciplinary proceedings with any players.
