Two weeks later in his hometown of Dublin, Kenna had a draw with the journeyman Paul King. After a period of inactivity, in June 2005 he won a points victory over former British and Commonwealth champion Julius Francis. In his comeback fight, he fought Wayne Llewellyn for the Southern Area heavyweight title. Llewellyn had a 30–5 record including a victory over Michael Sprott and a defeat to world title challenger Jameel McCline. Kenna won the fight and became the new Southern Area heavyweight champion. Later, he fought in Germany against hotly tipped prospect Oleg Platov. The lack of training and preparation on Kenna's part showed and the referee stopped the fight in the fifth round.
