Worcester Warriors have Argentina internationals Gus Creevy and Leonardo Senatore back in their squad as they wrap up their British & Irish Cup group games at home to Nottingham at Sixways.
Dean Ryan's Warriors have won all five B&I Cup games to date and one more can ensure a home tie in the quarter-final.
With that in mind, Ryan has named a near full-strength side, which includes Creevy at hooker.
England's Chris Pennell returns in a much-changed team at full-back.

|Gus Creevy and Leonardo Senatore helped Argentina to a first-ever Rugby Championship win against Australia, before defeating France and Italy in the autumn internationals.|
And flanker Senatore, who like Creevy has been away on autumn international duty with the Pumas, is on the Warriors bench.
There could also be debuts for replacements Alex Gordas and Heath Stevens, who has been absent with a pre-season injury.
Meanwhile, the Warriors have opened their fourth Junior Academy Centre in Shropshire - at Telford College of Arts and Technology.
Warriors have already launched centres at King Edward's School in Birmingham, Barkers' Butts in Coventry and Luctonians, in Herefordshire.
Worcester Warriors: Pennell; Smith, Stelling, Mills, Biggs; Lamb, Arr; Rapava Ruskin, Creevy, Daniels; O'Shea, Williams; van Velze (capt), Betty, Thomas.
Replacements: George, Bower, Gordas, Senatore, Mulchrone, Symons, Stevens.
