A massive AFL study which promised to make “groundbreaking” findings about concussion resulted in no published research and “confusion” about what happened to tests performed on players, a review into the work of the league’s former concussion adviser, Dr Paul McCrory, has found.

On Tuesday, the AFL apologised to players involved in the study and admitted they were “let down”.
