The Knights head west to face County rivals Yorkshire Carnegie for the first time since last season’s play-off semi-finals hoping to repeat the result from the last trip to Headingley Carnegie.
For the clash DoR Clive Griffiths has kept faith with the backline that started in the 29-23 win over London Scottish last time out.
The pack, however, sees many changes including a full change of personnel in the front row. Robin Hislop gets the nod at loose head with Ben Hunter at hooker and Colin Quigley makes his first of the season at tighthead.
Matt Challinor and Dave Nolan continue at lock in front of a changed back-row where Latu Makaafi is recalled to the blindside alongside Tigers dual-registered flanker Will Owen and former Carnegie man Jarad Williams switches to eight with Alex Shaw missing the tie with a shoulder injury.
There is plenty of forward firepower on the bench with front row replacements in the form of Richard List, Harry Allen and WillGriff John.
Harrison Orr arrives from Kingston Park and could make his debut, the former Ealing and Australia U20s man can provide cover right across the back five.
Back replacements come from Dougie Flockhart, Simon Humberstone and Sam Edgerley; the trio ensuring that the coaches have plenty of options out wide and in the half-backs.
Kick off tomorrow is at 20:00 & full text commentary will be provided on Twitter.
