The AFL and Western Bulldogs say they have not been notified of legal action by the former premiership player Liam Picken, who alleges he was allowed to continue to play despite concerns about cognitive impairment from concussion.
In a writ lodged with the court on Wednesday, the 2016 premiership player claims he repeatedly flagged concerns he was suffering symptoms after being concussed, but was never sent to an expert for help and was allowed to continue playing.
