With Jukurit not in action, JYP knew another win inside 60 minutes would see them return to first place, and they once again lead the Mikkeli side on goal difference thanks to their 3-1 win in Lahti. Having started with successive wins, it's three defeats in a row now for Pelicans.
Carl-Johan Lerby had the home side ahead but strikes from Daniel Torgersson and Leevi Tukiainen had JYP in front before the end of the first period, and that's how things stayed until the final minute, when Aaro Vidgren ended the contest with an empty-net goal.
After JYP and Jukurit on 15 points each come Assat in third place, three points further back, after the Pori side won 2-1 at home to Kiekko-Espoo to extend their winning run to four, while KE sit ninth after back-to-back losses.
Balazs Sebok had his opener cancelled out late in period two by Connor Corcoran, but when Johan Olofsson put Assat ahead for the second time in the third period, the visitors had no reply.
Newcomers Jokerit are having a dreadful campaign so far, losing five out of five and only picking up one point. Their latest defeat was a 6-0 drubbing at the hands of champions Tappara, who themselves only have two wins from four played.
With a performance that may kickstart their title defence, Tappara had five players earn two points as Tomi Sallinen and Olle Strandell grabbed a goal and an assist each, while Christian Heljanko made 22 saves at the other end for his first Liiga shutout this season.
Jokerit are now bottom of the table after KooKoo became the 17th and final team to earn a point this season - Samuli Niinisari's overtime goal gave SaiPa a 2-1 win that keeps his side perfect with four wins from four, albeit two came after the 60-minute mark. A better goal difference lifts KooKoo above the Helsinki side.
There was more disappointment across the capital as IFK Helsinki fell to a 3-2 loss at home to Lukko thanks to Alex Beaucage's overtime winner, while Hameenlinna won 3-1 at home to TPS Turku for a second win of the season, and Karpat held off the challenge of Vaasan Sport to win 3-2 to move up to 10th.
