And there is largely good news on the injury front for Saints, who will welcome back Courtney Lawes from his enforced rest week.
Boyd said: "Piers Francis is still another week away, but Tom Wood is available.
"Ahsee (Tuala) is probably not quite ready for this week, probably next week.
"We've still got the long-termers: Teimana Harrison won't be fit, Taqele Naiyaravoro won't be fit.
"But we're getting back to being in a not too bad position.
"Matt Proctor is probably going to be available - he's there or thereabouts.
"We've had a short week going from a Saturday to a Friday, which affects your preparation but I think we're heading in the right direction."
