The Sydney Roosters have suspended recruitment manager Peter O'Sullivan after the NRL advised the club it is investigating whether he is a fit and proper person for registration.

O'Sullivan is considered one of the best talent spotters in the game, having unearthed a slew of superstars including Greg Inglis and Israel Folau.

The Roosters have released the following statement: "Sydney Roosters CEO, Mr John Lee, confirmed that a Club employee is suspended. This is following the receipt of a notice from the NRL.

"Mr Lee indicated that the employee will be afforded procedural fairness while this matter is being dealt with. He also stated that the matter is subject to an appeal process.

"The Club will be making no further comment at this time."
