In February 2009, a magazine “The Ring”, considered Adamek as the best boxer in junior heavyweight. “The Ring” is one of the most prestigious periodicals on boxing, which gives a prize in a form of a championship belt to the best boxers from the specific categories.
On February 27, 2009, in the Prudential Center in Newark, in the presence of 12 thousand people, (including about 8 thousand polish fans), Tomasz Adamek won his first defense of the IBF Championship belt in junior heavyweight, with an American Johnathon Banks by TKO in the eighth round. The polish boxer not only defended the IBF belt, but won the belt from the less important federation IBO.
On October 18, 2009, Adamek officially renounced his IBF championship title to go to a heavier weight class, and fight against Andrew Golota for the IBF intercontinental belt at heavyweight. On October 24, in Lodz, Adamek defeated Golota by technical knockout in the fifth round
