The ‘Wolfman’ is understood to have bet on rugby league matches.
Manly winger David Williams is reportedly one of a number of players being investigated and facing suspension from the NRL over a betting scandal.
The 27-year-old was on Wednesday named by The Daily Telegraph as one of those to break the NRL’s strict gambling guidelines.
The NRL is also expected to sanction other players for placing bets on rugby league after an investigation by the organisation’s Integrity Unit.
There is no suggestion of match fixing, and it is believed Williams’ betting did not involved his Manly side.
The player, affectionately known as ‘Wolfman’, is understood to have placed multibets of NRL, soccer and AFL with betting in amounts as small as five dollars.
The NRL does not allow any of its players, coaches, referees, club employees or managers to take part in any sort of rugby league betting.
