Date of Birth: 3 January 1998, Bramming, Denmark.
Ipswich signed the young Dane in June as an injury replacement for German Michael Härtel. The 20-year-old won the Danish Under-21 championship in 2016 and 2018 was his first season in British speedway. He was with the Somerset Rebels in the Premiership earlier this year before being dropped as the management re-shaped the team. Jonas was replaced after two meetings as part of a triple team change for the Witches.
