Cardiff Blues have made three changes to their starting XV for the visit of defending Heineken Cup champions Toulon on Saturday.
The Blues were thrashed 44-29 by Exeter in their opening contest and things do not get any easier despite the fact they enjoy home advantage for the Pool 2 clash.
Robin Copeland, who came off the bench to score a try at Exeter last weekend, is rewarded with a spot in the starting line-up at No 8 this time round, with Andries Pretorius dropping out.
Director of rugby Phil Davies makes one further change in the pack as Tau Filise, who like Pretorius is injured, is replaced by Scott Andrews at prop.
In the back-line, Dafydd Hewitt is taken out of the squad to be replaced by Owen Williams, who will partner Cory Allen in the centres.
Toulon enjoyed a huge 51-28 opening win over Glasgow but have themselves made five changes for the trip to the Arms Park.
Jonny Wilkinson still captains the side from fly-half, and there is more English interest as both Delon and Steffon Armitage, the latter of which did not play against Glasgow, are named in the starting XV.
New Zealander Rudi Wulf comes in for David Smith on the left wing, while France international Frederick Michalak replaces Michael Claassens.
In the pack Armitage replaces Joe van Niekerk at flanker, while hooker Benjamin Noirot and prop Emmanuel Felsina both drop to the bench, being replaced by Jean-Charles Orioli and Xavier Chiocci respectively.
Toulon are big favourites to win but Cardiff may take some hope from the fact that they have already lost away to Oyonnax, Grenoble and Castres in the Top 14 this season.
