Scott Gibbs gave Wales an injury scare for Saturday's international in Paris when he was forced to sit out Swansea's 38-12 home win over Dunvant because of a trapped shoulder nerve.

Dunvant's misery was completed when Mefin Davies was sent off for persistent offside.
Another Wales player on song was Neil Jenkins who clocked up 33 points on his own in second-placed Pontypridd's 68-8 win at Caerphilly. Bridgend are a distant third despite their 45-14 thrashing of Newbridge, Llanelli drew 18-18 at Newport and Ebbw Vale were surprise 16-15 winners at Neath.

Two tries by Rowen Shepherd and one from his Scotland team-mate Bryan Redpath helped the champions Melrose to a 22-8 Tennents Championship win at Hawick which keeps them clear of Watsonians on points difference.Reuse content
