Northampton have made five changes to their side for Saturday's LV= Cup pool game against Saracens at Franklin's Gardens.
Although both clubs have qualified for the semi-finals there is the all-important matter of a home tie to be decided, with the winner of tomorrow's game all-but-certain of playing in their own stadium in March's knockout stages.
With 13 players away on international duty, and more on the treatment table, the Saints have recalled Jamie Elliott, George Pisi, Samu Manoa and Ben Nutley into the starting line-up, with Will Hooley making his first team debut at fly-half.
The former England U20 Junior World Championship winner has been on dual registration with Moseley this season, for whom he has made 11 appearances in the current campaign.
Meanwhile, Marcelo Bosch and Michael Tagicakibau come into the Saracens side, in what are the only changes to the back-line from last weekend's 41-8 victory over the Newcastle Falcons.
In the pack, Petrus du Plessis starts at tighthead prop, with Justin Melck packing down at number eight.
On the bench, Richard Barrington, Matt Stevens, Moritz Botha and Jacques Burger come into the squad with academy scrum-half Jack Maplesden also included in the matchday 23.
