In page Robert Helenius:

"

In January 2010 Helenius made the biggest step up so far of his professional career in squaring off against former WBO heavyweight champion Lamon Brewster. Many commentators wondered if the Brewster fight had come too early for the big Finn, however Helenius proved his toughness and punching power by grinding Brewster down to score a brutal TKO in the eighth round. Helenius went on to defeat Gbenga Oloukun on 26 March 2010 in Helsinki, despite breaking a bone next to the knuckles of his right hand.
