Hooker Vila Halafihi scored a hat-trick at the Skolars, while threequarters Alex Brown and Tom Ashton have also been among the tries of late.

Big signing from Championship side Newcastle Thunder, Mikey Wood, who put in a huge stint against London Skolars, is set to make his home debut against the Dons.
