This followed his sending-off for an outlawed tip-tackle in Saturfday’s win over Blaydon at the Woodlands.
He was represented by first team director John Greenwood, a solicitor, at the hearing.
The three-week punishment is at the lower entry point for such an offence.
A club statement said: “Fylde RFC and Ben are very grateful for a message of support from Blaydon RUFC submitted to the panel.
“His exemplary disciplinary record to date was another factor taken into account.”
