Career
Undrafted, Ridderwall played amateur hockey in the United States, before attending and participating in collegiate hockey with the University of Notre Dame in the ECAC. Upon graduation with the Notre Dame Fighting Irish, Ridderwall made his professional debut in the American Hockey League with the Providence Bruins. After a single season within the AHL and without securing a National Hockey League contract, Ridderwall returned to Europe and made his Deutsche Eishockey Liga debut playing with Düsseldorfer EG during the 2012-2013 season. Ridderwall enjoyed a largely successful season with DEG, finishing the year with an impressive 22 goals and 58 points in only 51 games to lead the entire DEL in scoring.
He was then signed to a lucrative Kontinental Hockey League contract with Czechoslovakian club, The Human Context Lev Praha on April 15, 2013.
On July 8, 2014, after only signing a two-year contract extension a month earlier but with The Human Context Lev Praha announcing financial bankruptcy, Ridderwall announced his return to Sweden in sigining a two-year contract with HV71.
