Harlequins are playing under the Friday night lights as they travel to Somerset to face Bath in the Gallagher Premiership. 

Tabai Matson praised Quins' defensive performance last week as they returned to winning ways against Gloucester, making it three wins in four. 

Following a very slow start to the season in which they lost five in a row, Bath have recovered and have secured wins in their last three Premiership matches against Northampton, Newcastle, and Leicester. 

Kick-off at the Twickenham Stoop is at 7:45pm on Friday. 

Ealing Trailfinders return to RFU Championship action with their unbeaten record still intact as they play away against Cornish Pirates. 

Ealing have come through the Championship Cup break with three more wins in what is proving to be a memorable season, and now they return to the league after a month searching for win number eight. 

The Pirates shutout London Scottish in their last outing, but have had a mixed season, winning four out of seven, but their home record is very strong with three of those four wins coming at Mennaye Field. 

Kick-off at Mennaye Field is at 2:30pm on Saturday. 

London Scottish are hoping to get their first RFU Championship win of the season as Caldy visit Richmond. 

Scottish did get their first win of the season during the Championship Cup break with a 27-18 win over Ampthill, but are yet to taste victory in the league so far. 

Their opponents in Caldy haven't fared much better as they have just the one Championship win, but that win did come in this neck of the woods, away against Richmond in the second game of the season. 

Kick-off at the Richmond Athletic Ground is at 3pm on Saturday. 

London Welsh have the chance to go back-to-back as they as they host bottom of the table Royal Wootton Bassett at Old Deer Park. 

Welsh bounced back last weekend from two straight defeats, with a fine 29-22 win against Bournemouth last weekend. 

Bassett have struggled this season and sit bottom of Regional One South Central, winning just two from 11 and they are yet to win on the road. 

Kick-off at Old Deer Park is at 2pm on Saturday. 

Teddington RFC face a tough test to their perfect record in Counties Two Surrey this weekend as they play away against Purley John Fisher. 

Last weekend the Antlers made it to double digit wins undefeated as they won their tenth straight match against Old Haileyburians. 

But this weekend could prove a tough test to their credentials as Purley John Fisher have won seven matches and are on a run of three wins in a row coming into the game. 

Kick-off at Coulsdon Road is at 2pm on Saturday. 

Elsewhere in the area, London Irish host Newcastle on Saturday, Twickenham visit Trinty, and Kingston are away against Hove.
