Clive Griffiths will inject experience into the Knights’ backs as he looked to touch down one foot in the Championship at Rosslyn Park this afternoon.
Knights stalwart Chris Hallam will start at scrum half in the club’s biggest game of the season.
And leading points scorer Dougie Flockhart returns on the win with Paul Jarvis switching to full back.
Griffiths has named the same pack that comfortably saw off Old Albanian at Castle Park last weekend.
Victory for the Knights would put them a minimum of ten points clear with three games to go.
But should second placed Rosslyn – who current sit seven points adrift – take the win, they would throw the race for promotion wide open once again.
The London side have lost just once at home all season while their 24-17 defeat at Castle Park was one of just four losses they have suffered all season.
Knights to face Rosslyn Park: Jarvis, Flockhart, Clark, Armitage, Lewis, Roberts, Hallam, List, Santamaria, Davies, Challinor, Parsons, Walker, Hills, Jones.
Replacements: Brugnara, Sodini, Kettle, Bryce, Bravo.
