Picken has improved with his syptoms but will not be ready by season’s end. Club medical staff and specialists are happy with the progress the 31-year-old has made.
Picken has been training without contact for the last eight weeks and is holding up well. The measures that need to be take before Picken can make his return are extensive.
With such little time left in the 2018 season and the unlikelihood of playing finals, the Bulldogs will shift their energy on preparing Picken for a return in 2019.
“I’m encouraged by the progress I’ve made and I’m very lucky to have been looked after by such a great team of medical experts,” Picken told the club’s website.
“I have been blown away by the support of my family, team-mates, the Club, and by all of the messages I’ve received from Bulldogs fans and the wider football community.
“I will take the extra time to dedicate to my recovery and will now look ahead to next season.”
