There is a real buzz about the camp now that we are at the quarter-final stage of the Challenge Cup.

When you get this far, you begin to sense that the final is within reach - and that means a trip to Murrayfield.

This is a massive game for us. We want to keep hold of our trophy, but we know it will be just as hard as ever.

Halifax are a tough proposition but we know that we should win if we perform like we know we can.

The key is to defend well. We did that against Salford in the Super League last week, stopping them from scoring a single try.

But we will be tested again by the Blue Sox and we need to make sure we stay solid.

Daryl Cardiss is a threat. He is one of the quickest players around and we must prevent him from getting up a head of steam.
