Following the sitting of an independent doping tribunal this afternoon, a suspension of 15 months has been handed down to Ryan, who tested positive for a recreational drug.
The player tested positive in A and B samples for a banned substance under the Association's Doping Control Regulations and in line with the process set out in the regulations the matter was referred to the Independent Doping Tribunal.
The determination of the Tribunal was that a doping offence had been committed and a 15-month suspension was imposed. Any appeal must be lodged within seven days.
Shamrock Rovers and the player himself have yet to release a statement.
