The Lions are also set to be without Danny Bridge for Sunday's Kingstone Press Championship fixture with Hunslet Hawks.
Swinton coach Gary Chambers said: "We need to build a bit of consistency now, and that could make all the difference when the league is close like this. A quick fix won't get us where we need to be."
Hawks coach Barry Eaton insists his side will not be targeting specific fixtures as they search for a fourth win of the league campaign.
Eaton said: "Every game is just as important as another. We've had a look at the table, but we just concentrate on performance. We're only nine games in, so there's still a long way to go."
