Honor suffered a thumb injury during the Northern Rail 9s but Massara thinks he “will probably play”.
Massara said: “Over the last few weeks our changes have come in attitude more than anything.
“There’s a really good work ethic, and people are buying into things fully. It’s been building for a while – now we need to keep practising those things.”
On Doncaster, Massara added: “They’ve got a few new additions and we know they’ve been going pretty well.
“We’ll treat them with the utmost respect, as we do everybody. They’ve just got Ben Jones on loan, so we know a lot about him, and they’ve got some other guys like Chris Spurr who we’ve faced earlier in the year.”
