He then had spells with King's Lynn Stars and Wolverhampton Wolves in the top flight of the British League, before joining long-time sponsor Ivan Henry's new club Arena Essex Hammers in 1991.
Petersen achieved a calculated match average of over eight points per meeting in the top flight, but announced his retirement at the end of that season.
During 1993, a serious head injury to Peter Ravn led to Petersen returning to the Hammers to cover his fellow Dane's absence.
Petersen, disgusted by off-track incidents, threw his runners-up medal into the crowd at the end of the meeting.
He made one further appearance on a bike at Arena Essex when he rode for a Hammers Dream Team in the Andy Galvin Benefit Meeting in March 1995.
