The Knights squad is now 17 strong following the signing of former Plymouth Albion fly half Paul Roberts.
Clive Griffiths’ summer rebuilding project is now well underway with the addition of another impressive name in Roberts.
The 23-year-old was Plymouth’s top points scorer last season and featured in 20 of their 22 games.
Roberts made two appearances for Premiership side Bath and skippered their A side before switching to Plymouth.
Knights head coach Glen Kenworthy believes the Liverpudlian will make a big impact in National One.
“Paul is a player with very recent fop flight experience and has proved he is a real threat in the Championship which reads very well for the Knights and our assault on National One,” Kenworthy said.
The addition of Roberts comes hot on the heels of a trio of signings, including two from overseas.
Pacy Argentinian scrum half Bruno Bravo has arrived from San Albano in Buenos Aires.
The 24-year-old is now the third number nine at the club along with Chris Hallam and James Munro and will be looking to secure the starting berth after skippering his previous club.
Bravo has been joined at Castle Park by another former club skipper in hooker Roberto Santamaria.
The Italian previously captained Aironi in the RaboDirect Pro12 and Heineken Cup.
Burnley-born second row forward Michael Walker-Fitton has also signed for the Knights, joining from French side RC Chateaurenard.
