Craig Sives has renewed his contract at Shamrock Rovers, taking him into his third season with the Airtricity Premier Division champions.
The 25-year-old Scot agreed terms with manager Stephen Kenny on Thursday.
Sives joined Rovers in 2009 after an injury interrupted spell at SPL side Hearts and was named young player of the year during his first season with the Tallaght side.
He has won back to back league titles since arriving in the League of Ireland.
Meanwhile, Rovers have announced that full-back Pat Sullivan will not play for the club during the 2012 season.
The defender, signed from Cork City in 2009, has decided to take time out from football and will instead tour Australia.
Sullivan went down in Rovers folklore during the 2011 season when he scored the vital goal which sealed a passage past Partizan Belgrade and into the Europa League group stages.
Earlier this week, Rovers confirmed the signings of Sean Gannon, Dean Kelly and Conor McCormack.
