Jakob Blåbjerg Mathiasen (born 11 January 1995) is a Danish former professional footballer who played as a defender.
[2] In September 2012, Blåbjerg signed his first full-time contract and was to be promoted to the first team squad from the summer 2013.
[3] He got his Superliga debut for AaB in February 2013 against Silkeborg IF alongside Kasper Pedersen, as the four regular options for the centre-back position were all out with either injuries or bans.
Blåbjerg was promoted to the first team squad in the summer 2013 at the age of 18, but did not play any games the whole season while AaB won the league and the Danish Cup.
[7] Aalborg University had a collaboration with AaB, so when Blåbjerg was in Dubai with the Danish U21 national team, he took an exam through his computer.
