The battle for promotion from the Championship saw Bristol and London Welsh qualify for a two-legged final with their results over the weekend.
Favourites Bristol overcame a stubborn Rotherham Titans side to earn their place in the final. Making his debut for Bristol was Ryan Jones, who had an inspired debut.
London Welsh beat off the challenge of Leeds Carnegie at the Kassam Stadium thanks to a late Gordon Ross penalty.
The final will be played over two legs, the first leg will be played at the Kassam Stadium, Oxford on Wednesday 28th May (KO 7.45pm) and the second leg will be played at the Memorial Stadium, Bristol on the following Wednesday evening (7.45pm).
The aggregate winners will then take their place in the Aviva Premiership for 2014-2015 in place of relegated Worcester Warriors.
We have several players interested in these games. Dwayne Peel has now left Sale Sharks after six years service to join Bristol and Jonathan Mills, Tom Arscott, Phil MacKenzie and Kirill Kulemin will all be hoping that their former club London Welsh make a return to the Premiership.
Sale Sharks' European campaign this season has been a case of what might have been but back-row forward Mark Easter insists he and his teammates can hold their heads high even if it ends without a win.
Danny Cipriani has been called up to the England EPS Squad ahead of this season's Six Nations, and Ross Harrison has been called up for the England Saxons squad for their match against Irish Wolfhounds on Friday 30th January.
Steve Diamond has admitted that the experience of this season's European Rugby Champions Cup has made him and his squad even more determined to finish in the Top Six of the Aviva Premiership and so book their passage into next season's European showpiece.
Sharks were left empty handed after a tremendous effort against Clermont Auvergne in appalling conditions at the AJ Bell Stadium. So close but yet so far in the home games in the competition with Steve Diamond's men running Munster,Saracens and Clermont right to the bell on each game.
