Wallabies and Waratahs hooker Tatafu Polota-Nau says he’ll keep playing union after recovering from the most recent of a string of head knocks in his career.

The 29-year-old was ruled out for five matches after being knocked out during the Brumbies clash last month.

It was the second head knock to rule him out of games this season and the most recent of a long list of concussions in his career.

Former Wallaby Peter FitzSimons has since urged Polota-Nau to retire from the sport following the most recent concussion.

Polota-Nau thanked him for the concern but says he’s not ready to hang up his boots.

“If anything he is definitely concerned about me, which is great,” Polota-Nau told the Waratahs’ radio podcast.

“For me really I understand what goes on with it … I still think there’s lots of footy left in me.”

Polota Nau has been recovering in line with the ARU’s concussion protocol and joked doctors told him “there’s still a brain in there and it’s still functioning”.
