PORT City lock Daniel Dumas has been stood down by Group Three Rugby League pending an investigation into him playing in Queensland with Mackay last year.
Dumas returned to Port this season.
"Daniel Dumas played with Taree City in 2012, when he was the captain-coach,'' Group Three secretary Barrie Smith explained.
"He then played in Queensland last year with Mackay without getting a clearance from Taree City.''
It has been alleged that the Queensland club changed the date of Dumas's birthday so his registration could be lodged on the player data base.
Dumas was working in Queensland at the time.
He returned to Port Macquarie this year and resumed playing with the Breakers, again, it is claimed, without a clearance from the Bulls.
Mr Smith said Dumas has been stood down until Group Three gets advice from the Country Rugby League on how to deal with the matter.
Dumas played for the Breakers last week in the club's first win of the season when they accounted for Wingham.
It is not known if the points from that match will now stand.
