It is a second professional deal for the 20-year-old, who last year also penned a 12-month contract.
Concannon, who hails from Hagley, has been with the Club since the age of seven.
He is best at home in an attacking midfield role.
A clever, technical player blessed with quick feet and good awareness, Concannon has an eye for goal too due to his shooting prowess and timing when arriving onto things in and around the box.
A regular for Blues Under-23s, Concannon made his First Team debut in the FA Cup tie against Coventry City.
