Port Adelaide star Robbie Gray has been stretchered off following a sling tackle from Fremantle forward Ryan Nyhuis.

Early in the third quarter, Gray was dumped in a tackle on the wing, and lay motionless before being stretchered off the field.

Nyhuis is likely to be cited by match review officer Michael Christian, with player safety at an all-time high.
