Mad Dog on international duty for the first time as a Town player
The Danes are at home to Iceland in Herning on March 24 and then play Scotland at Hampden Park five days later.
Jonas, who has been a regular in the Town side since arriving last summer, will meet up with his international team-mates after Blues’ game against Rotherham next weekend.
Mad Dog, as he is known by his team-mates at Portman Road, has been capped twice by Denmark but this is his first call up to the full squad as a Town player.
