The Knights have signed Cameron Cowell on a dual registered season-long loan from Newcastle Falcons.
The 21 year-old featured seven times in a Donny shirt, with his first game coming in November, before returning to the North East in the summer.
Cameron has played 38 matches for England World Cup sevens, where he made nine tries and added a further 32 conversions.
Blessed with pace and lighting feet, Cameron can play at either wing or full-back and spent time in the London Irish academy as a youngster.
The London-born back scored three tries in an impressive stint at Castle Park last season and will look to extend that tally in the upcoming campaign.
Director of Rugby, Clive Griffiths was happy to get Cameron in the squad ahead of tonight's Sale Sharks game. "He’ll add pace to the back three and add to the strength in depth in those positions."
Ruaridh Dawson and Curtis Langdon have also signed on a dual registration with the Knights and could feature in the friendly with Sale Sharks.
