Opdal was Brann's first choice until Piotr Leciejewski arrived at the club in 2011, and when his contract expired after the 2011 season Opdal was not offered a contract renewal. Still without a contract, Brann wanted to sign Opdal on a short-term contract in May 2012 as both Leciejewski and Jørgen Mohus were injured, but Opdal rejected Brann's offer due to a knee-injury. Opdal joined the Danish Superliga side SønderjyskE in June 2012, and made his debut for the club in the 6–1 win against Randers in the opening match of the season.
