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.
