In May 2001, he won the Polish Heavyweight Championship by beating Ratko Draskovic via unanimous decision and on July 20, 2002, he was given another shot at the European title against the unbeaten defending champion Luan Krasniqi.

In his first defense of the European Championship title three months later, he met Sinan Samil Sam and was knocked out in the seventh round.

In his last bout before retirement from the sport, he defeated American Ed Perry by unanimous decision in February 2006 to bring his record to 43 wins and 7 losses.

On June 2, 2007, Saleta made his mixed martial arts debut against Belarusian opponent Martin Malhasyan at KSW VII.

Despite his retirement from professional sport, he then returned to action after calling out fellow ex-boxer Marcin Najman at KSW XIV in September 2010.

Personal insults in press happened regularly before and even after the fight, which Saleta won by submission due to a forearm choke.
