WORCESTER WARRIORS (2nd) v CONNACHT (1st), Sixways Stadium, 3pm
Team News: Connacht have made two changes for their Amlin Challenge Cup Pool 2 match against Worcester Warriors on Saturday.
New Zealander George Naoupu comes in at number 8 for his Connacht debut, while Ray Ofisa replaces the injured Johnny O'Connor at openside flanker.
The westerners have been forced to make one late change to their matchday squad, with replacement hooker Adrian Flavin ruled out because of illness. His place on the bench will be taken by Galwegians youngster Dermot Murphy.
Connacht coach Michael Bradley describes Naoupu as a 'hardened professional' and 'a serious option'.
Meanwhile, Scottish centre Alex Grove returns from international duty as the Worcester Warriors tackle Connacht at Sixways Stadium.
Grove makes his first start for the club since early November after impressing for Scotland in the autumn internationals against Fiji, Australia and Argentina. He is one of two changes to the starting line-up that drew with London Irish in the Guinness Premiership last time out.
Hooker Chris Fortey is handed a starting spot in the front row, with Aleki Lutui moving to the replacements bench.
There are three changes on the bench - Jordan Page is selected and Graham Kitchener returns after a back injury ruled him out of the trip to Reading last weekend.
Fit again out-half Matthew Jones is also handed a place among the replacements and could make his first senior appearance at Sixways since facing Brive in the Challenge Cup quarter-finals last April.

Pre-Match Quotes: Michael Bradley (Connacht) - "We would look at this tournament different from the Magners League. We played very well last week in patches (against Cardiff), but didn't get the rub of the green.
"You need to look at these two competitions in isolation. Connacht historically have done very well and enjoyed the European Challenge Cup, so that's the way we look at it.
"We had Harlequins over here and Worcester, and beat both of them. We lost to London Irish, Sale and Bath, but they were all good contests here, so we know what to expect, and this time around it will not be any different.
"Connacht do well in Europe, we seem to rise to the challenge, and the fact that if we win the group - and we are in a good position to win the group - we can get a home quarter-final, but we have to take that opportunity and be quite focused on it.
"Worcester are extremely physical at the breakdown. They boast a large, strong and physical pack, while their backs are laden with individual talent that you cannot afford to give them space. Montpellier travelled there and beat them by standing up to their pack."
"It is going to tougher than it should have been at this stage and Connacht are the form team and the side to beat.
"They went to Montpellier and won, they will be coming here targeting this competition and looking to build on an excellent victory in France.
"I've picked a very determined team and one I will put pressure on to keep some momentum. Hopefully we will meet that challenge, get a victory and a try or two.
"Ourselves and Connacht, we will certainly know each other inside out after these two back-to-back games, but we have also got a very tough Guinness Premiership fixture just around the corner against Northampton."
