Munster, who played predominantly as a fullback for the first four seasons of his NRL career, was a late inclusion at the back as cover for the injured Nick Meaney and didn't disappoint, scoring 20 points all up thanks to his three tries and four conversions.
Hughes, who suffered the injury late in the first half and played through to the break before being taken from the game, will have scans on Saturday, while the Storm will also wait to see what comes of Brandon Smith being placed on report for a hip-drop style tackle on 28 minutes.
