	After taking a five-year break from the sport, Tolppola returned to the ring on 9 May 2014. He would score three consecutive wins by unanimous decision before challenging unbeaten Matias Laitinen for the vacant Finnish welterweight title on 23 May 2015. Tolppola won a wide ten-round unanimous decision, but in September the result was changed to a no contest after he failed a drugs test for the use of hydrochlorothiazide (a diuretic to aid weight loss). The Finnish Professional Boxing Association subsequently handed Tolppola a two-year ban from boxing, effective from the Laitinen fight.
