BRISBANE father-son prospect Jaspa Fletcher will face a delayed start to his pre-season after suffering a back stress reaction. 

Fletcher, who could attract a top-15 bid on draft night, is tied to the Lions as both an Academy player and father-son, with his dad Adrian having played 107 of his 231 AFL games for the club.

He also played for Geelong, St Kilda and Fremantle, but Jaspa is only eligible to join the Lions and could be a first-round pick for the club later this month.

Fletcher had back soreness recently which has been diagnosed as a stress injury that will see him sidelined for the start of the pre-season and in a back brace for the next period.
