To date Cartha have 11 points from three completed games to lead the section while Watsonians, the holders, have 10 points from two games and are second in the pool.

This weekend will be exciting when Stirling County and Howe Harlequins, fourth and fifth in the pool respectively, meet.

That match has been moved to Lornshill Academy with Bridgehaugh unplayable.

In Pool B on Sunday there are also two matches.

Leaders Corstorphine, fresh from their impressive win at Hillhead Jordanhill, host third placed Stewartry Sirens.

The match has been moved to the 3G surface at Peffermill in the capital and Corstorphine head coach Eric Jones said: “We’re looking to build on last week’s performance.

“We haven’t played Stewartry in a year or so, but we’re expecting a tough game from them as always, with Suzy Rook back in the front-row, Lisa Ritchie at 10 and Chloe Johnstone in the centre we know they have threats around the park.

“We have to be more accurate in a couple of areas, so we’ve been working hard on those in training.”

Stewartry go into the game having beaten Ayr 37-0 last time out.

Heriot’s Blues are on the road to Ayr in the other Pool B match.

There are four National Plate matches scheduled for the coming days.
