St George Illawarra Head of Athletic Performance Nathan Pickworth returns for another SMAI High Performance Update ahead of the Dragons' Round 15 clash against the Eels at ANZ Stadium this Sunday.

Pickworth addresses speculation over the fitness of Dragons and New South Wales back-rower Tyson Frizell and the health of winger Kalifa Faifai Loa.

The loopholes that Shaun Nona has to jump through before he returns and how Will Matthews pulled up from his first run of the season is also touched on by Pickworth.
