When one door closes another one opens – and this week the door has opened for Carlton first-year rookie Blaine Johnson. 

Blues champion Heath Scotland was this week placed on the long-term injury list for the rest of the season, effectively ending his 16-year AFL career. 

The move has made way for a player to be upgraded to Carlton's primary list, and that player is Blaine Johnson. 

Johnson has impressed in his six outings with Carlton's VFL affiliate the Northern Blues. 

He has averaged 15 disposals per game and booted seven goals, including a four-goal haul in the Round 3 win over Footscray. 

The 18-year-old from Western Australia is a medium forward who presents well and can take a strong mark. 

Johnson arrived at Carlton after a stint with South Fremantle, where he played senior football in the WAFL.
