With the students out-of-action, second-placed Bargoed had the chance to close the gap at the top to two points heading in to the final weeks of the season.

The hosts ran-in seven tries through Ashley Norton, Rhys Humphreys, Ricky Cochlin, Adam Cullen, Lee Williams, Gareth Dare and Jamie Howells.
Llanharan replied through a brace-apiece by Elliot Foiles and Lee Thorne, but they were well beaten in the end, 52-31.
Caerphilly were relegated after they were destroyed by Blackwood at Glan yr Afon Park. Gareth Price and Mark Birkraer braces were among the nine Blackwood tries as they sealed the visitors' fate with a 61-7 triumph.

Tredegar. Shaun Robson bagged a double, and Nathan Hughes, Alex Webber and Mazin al-Azlani also touched-down for the hosts.
They are now level on points with Beddau, who played out a thrilling 32-32 draw with Merthyr.
Lewis Jones and Viv Owen both crossed twice for Beddau as they sealed what could turn out to be a precious two points.
Bedlinog can now begin to look ahead after confirming their safety with a 26-17 victory against Rumney. Martin Luckwell, Phil Cocharan and Martin Jones scored the hosts' tries.
Builth Wells pulled off one of the results of the season in Division One West as they beat third-placed Narberth, 19-17.

That result also saw Whitland confirmed as second place finishers, despite them being given a lesson in running rugby from champions Tonmawr.
