The Aviva Premiership clash at London Wasps has been billed as a "Cup Final" for the Exeter Chiefs, as they look to secure a top six place and an all-important Heineken Cup spot for a second season.
The Chiefs are obviously keen to play against Europe's top sides again and a win on Sunday would keep that dream alive.
Jeff Welch reports:
Yeovil Town's Championship survival hopes were severely dented last night, but Plymouth Argyle have edged closer to the League 2 play-offs.
All three of Devon's Football League teams suffered defeats, but Yeovil's Championship survival battle received a boost at Blackpool.
Exeter's Gareth Steenson missed a conversion attempt with the last kick of the match as Gloucester won 14-13 at Sandy Park.
