In August 2011, while training with Charlton Athletic, Rasisk scored a penalty on his first appearance, in a friendly match against Carshalton Athletic in a 2–1 defeat.
However, Rasiak left Charlton following his trial when the club decided instead to sign fans favourite Jason Euell to bolster their attack and Rasiak returned to Poland.

One month after leaving Charlton, Rasiak returned to Poland, joining Jagiellonia Białystok.
The move was delayed by his previous club AEL Limassol failing to send documents which prompted FIFA to intervene.

On 3 December 2011, Rasiak made his debut for Jagiellonia Białystok in a 2–0 defeat against Podbeskidzie Bielsko-Biała.
On 11 December 2011, Rasiak played his second match where he scored his first goal for the new club in the 1–0 away win over Lechia Gdańsk.
It was his first goal in the Polish league for 7 years.
