Cardiff v Connacht, Arms Park 5.30: Connacht, looking for their third successive win over Cardiff in as many years, arrive in the Arms Park with an unchanged side from last week, coach Michael Bradley showing faith in the ability of his durable team.
There is just one change among the replacements, with Fabien Boiroux being called up for the injured Dan McFarland.
As always, since the proposal to put the "fourth" province out of business, Connacht will arrive in Wales defiant and seeking the same vigour that gave them an opening 11-3 Celtic League win over Edinburgh Rugby.
Cardiff keep their back division intact, but introduce six changes to the forwards, four personnel and two positional.
They lost 12-23 in their first game last week, also against Edinburgh Rugby. In fact, of the five Welsh teams, who have arrived on the scene following the instigation of a more streamlined professional structure in Wales, they were the only side to lose.
Into the team comes Ben Evans at tight-head prop, Dan McShane at lock and Rob Appleyard and James Malpas in the back row. The positional changes see Ken Fourie move across to loose-head prop and Dan Baugh switched to open-side flanker.
Welsh second row, Craig Quinell, who was red carded last week after 82 minutes and subsequently suspended is the biggest loss to the Welsh side.
CARDIFF BLUES: D van Vuuren; N Walne, J Robinson, N Macleod, D Dewdney; N Robinson, A Moore; K Fourie, A Lewis (capt), B Evans, D McShane, A Moore, R Appleyard, J Malpas, D Baugh.
CONNACHT: M McHugh; C McPhilips, D Yapp, T Allnutt (capt.), W Munn; E Elwood, C Keane; W O'Kelly, B Jackman, A Clarke, D Browne, D Farley, M Swift, D O'Sullivan, M Lacey.
