The City of Pori and his former youth team, Porin Assat, presented Kotkaniemi with special commemorations.
The 26-year-old excelled during his time with Porin Assat, including making his debut with the under-20 team when he was just 15 years old.
After the presentation at the arena, fans in attendance had the opportunity to take a photo with Kotkaniemi and the Cup.
Kotkaniemi also took the Cup to his former elementary school, then brought it on a quick ride on a jetski on the lake.
