Anthony Watmough is sitting on a knife edge at Manly Sea Eagles after a string of professional misdemeanours.

Watmough and Seu Seu were arrested in Manly at the weekend for urinating in public, and have both been fined, suspended from this week's match and docked a week's pay.

Watmough has already been in trouble for losing his licence due to speeding and being involved in an altercation with a sponsor of the club in 2009.

One more run-in could mean the end of his career at Manly.
