in april 2016, tolppola announced his intention to appeal the decision, maintaining his innocence and calling into question the association's testing procedures. this appeal was rejected by a court in june of that year, who determined that there were no sufficient grounds for lifting his ban. boxing promoter joona jalkanen announced in october that tolppola would return to the ring immediately after his ban was lifted, on 13 may 2017, and would be looking to challenge for a european title at some stage, but the fight did not take place.
