The Hoops have secured the services of the Ireland youth international, who has agreed to extend his time at the club
Shamrock Rovers have confirmed that Sean Heaney has committed to the club for another season.
The 20-year-old Republic of Ireland youth international came through the Rovers ranks and established himself in the first-team in 2016.
Heaney made 20 appearances in all competitions, including the Europa League, last season, finding the net on three occasions.
The Dublin native made his breakthrough at Tallaght after spending a season on loan at Shelbourne in 2015 and he is considered a bright prospect by Rovers head coach Stephen Bradley.
The Hoops have added 10 new faces to their squad ahead of the 2017 campaign and Heaney joins nine other players who have extended their time in south Dublin by signing new contracts.
