Bristol United have played twice so far in this season's A league...
Exeter Braves 28 - Bristol United 19
Bristol United 24 - Bath United 47
Both matches have been exciting games and the Bristol side are keen for a first win in front of home fans.
Kick off tonight is at 7.15pm and with a well stocked bar and good weather forecast, tonight's flood-lit contest on Clifton Rugby's stadium pitch is shaping up to be a great start to the weekend.
A structural reshuffle to the Premiership Rugby A League will see 13 teams compete before the semi-finals and finals in April 2018.
The six-team north pool will play each other, both home and away, with the top two progressing to the semi-finals, whilst south pool sides will play each other just once.
From there, the top five after six matches from south pool will meet again, and play an additional four games in a second phase mini-league with the top two reaching the semi-final stage.
The semi-finals will take place on the week commencing 22 April, with the final set to be played on Monday 30 April 2018.
