Ulster have also named their team ahead of their Edinburgh clash
Pro12 League Leaders Connacht and Ulster have both named their teams ahead of tomorrow's games against Cardiff Blues and Edinburgh.
Connacht travel to the Welsh capital, after last week's win in Limerick and make eight changes for the game. Darragh Leader comes on to the right wing for his 50th Connacht appearance while Tiernan O'Halloran shifts to fullback. Jack Carty is named at outhalf and scrum half Ian Porter earns his first Pro12 start of the season.
There is a new front row with the introduction of Ronan Loughney, Dave Heffernan and Rodney Ah You while Quinn Roux returns from injury to partner Aly Muldowney in the second row.
Captain John Muldoon will become the first player to break the 200-cap barrier in the Pro12 when he leads the side out in the Welsh capital tomorrow night.
Rob Herring, who signed a two-year contract extension earlier this week, will replace Rory Best as hooker and captain for Ulster as Les Kiss continues to manage his playing resources ahead of the Edinburgh game.
The 25-year-old is joined in the front row by Ricky Lutton, who will make his first start of the campaign, and Kyle McCall.
Franco van der Merwe and Roger Wilson return to the side at lock and number 8 respectively, while Ireland internationals Dan Tuohy, Chris Henry and Iain Henderson make up the rest of the pack.
Luke Marshall is given an opportunity in midfield beside Darren Cave, with Rory Scholes due to start in a back three that also features Andrew Trimble and Peter Nelson.
