Correction to: Chronic traumatic encephalopathy in two former Australian National Rugby League players.

In the original publication of this article [1] the term 'National Rugby League (NRL)' was used to refer to professional rugby league competition sport in Australia. The term should have read 'professional rugby league' to include the various professional competition nomenclatures over the last fifty years, including but not limited to NRL. In this correction article, the incorrect and correct information are published.
