Cronulla captain Cameron McInnes is not surprised more than a third of NRL players continue to train after suffering concussions, but hopes change will come to prevent long-term health impacts.

A players' union survey found that close to one-sixth of NRL players were still hiding concussion symptoms, along with six per cent of women's players.
