WORCESTER Warriors' new arrival Bryce Heem will dive straight into action for his new side when they host Newcastle Falcons at Sixways tomorrow in the Aviva Premiership (3pm).

The Kiwi, who joined from Super 15 side Waikato Chiefs, forms a potent back three alongside full-back Chris Pennell and fellow winger Cooper Vuna.

There is a recall in midfield for Alex Grove, where he will link up with Ryan Mills.

In the forwards, Val Rapava Ruskin earns his first start in the front row this season alongside Niall Annett and Nick Schonert.

Darren Barry is back in the starting line-up in place of Tevita Cavubati to partner Donncha O'Callaghan, while the back row remains unchanged with Phil Dowson, Marco Mama and skipper GJ van Velze.

Georgian hooker Jaba Bregvadze could also make his Warriors debut from the bench.

Falcons have made five changes to their starting XV with three new faces in the back-line and two in the pack.

Argentina international Juan Pablo Socino makes a first start of the season for the club at inside centre, taking over from Adam Powell.

Chris Harris returns from injury to outside centre for Tom Penny.

Alex Tait switches from wing to full-back with Alesana Tuilagi taking the vacated number 11 shirt.

In the pack, a straight swap at loosehead prop sees club stalwart Rob Vickers take over from Eric Fry.

A change in the second row sees Kane Thompson return to partner former England lock Mouritz Botha.
