Abbasi started his career at Fajr Sepah, before joining Shirazi club F.C. Fajr Sepasi. He displayed great form there and was called up to the Olympic team and eventually national team because of it. With more impressive performances he was noticed by the bigger clusb in Iran and was signed by the powerhouse Esteghlal F.C.. The competition for him was too much and he moved to Sanat Naft F.C. for the 2002-03 season. He was one of few non-Abadani players who was supported by the passionate Naft fans, but left after one season, returning to Esteghlal F.C.. His stay there was once again very short and he left Esteghlal for Sepahan F.C.. He was eventually able to regain his old form and was called up again to the national team during the same time. Esteghlal's fierce rival, Persepolis F.C. signed him in 2005. He is currently playing forr the club, despite rumors at one one point, stating that former Persepolis manager, Arie Haan, wanted him out.
