Only Oldham and Barrow take 100% records in to the third round of Championship 1 this weekend.
Nathan Mossop (shoulder) faces a late fitness test before Scorpions coach Dave Clark can settle his team to travel to Doncaster.
But Clark’s squad will definitely include Alan Pope, who missed last week’s 24-22 win at Wath Brow after his wife gave birth.
Clark said: “It’s going to be a huge challenge for us at Doncaster. We need a good performance, and if we can get to a completion rate like we did against Wath Brow, when we were up to 80 per cent, then we’ll compete well.
“Doncaster are looking at promotion and finishing in the top four. If you look at the personnel they’ve got, they’ve got a wealth of experience.
Gateshead Thunder v Whitehaven (Sun, 3.00pm)
Neighbour could be further boosted by the return of Ryan McBride, who has been able to “step up in training” and “might have a chance for Sunday”, according to the Thunder coach.
However, Tabua Cakacaka remains a fortnight away from making his own return to first team duties.
Neighbour said: “We played Whitehaven in the Northern Rail Cup and they’re a traditional Whitehaven side – they’re fairly big in the middle, and they’re very happy to shift the ball around.”
Haven coach Don Gailer has warned his squad not to underestimate the threat Gateshead pose.
He said: “They’ve gone close a couple of times. Sometimes you’ve only got to win one game to turn things around, and they knocked off York Acorn last week.
“They’ll be a lot better than they were when we met earlier in the year.”
Gailer will check on the fitness of two players suffering from flu before finalising his squad, although he is keeping the identity of the mystery duo close to his chest.
Griffiths said: “Our attitude was spot-on last week against Toulouse, and it will need to be again when we face Rochdale.
“I’ve watched them on DVD and they’re a very capable outfit with good players in key positions.
Danny Davies (whiplash) is also doubtful after being involved in a road accident.
Stankevitch added: “If we get beat, we’ll have been beaten by the better team on the day because we’re taking a strong side to Wrexham.”
Oldham v Barrow Raiders (Sun, 3.00pm)
John Gillam remains sidelined with a toe injury and Chris Murphy (knee) is also doubtful, but Oldham coach Tony Benson expects to have an otherwise full-strength squad for Sunday’s fixture with Barrow Raiders.
The top-of-the-table Co-operative Championship One clash will bring to an end at least one of the only two 100 per cent records in the division.
And Benson believes his men are ready for the step up in intensity.
He said: “It’s first versus second, and it’s going to give us both an idea of where we’re at.
“Barrow’s attack is pretty formidable, and they score tries from all over the field.
“Your defence has got to be pretty good, and I think at this stage ours is. We’re ready for a game like this.”
Coach Darren Holt, who is hoping to have at two players return from injury on Sunday, said: “We had a 100 per cent completion rate in the second half (against Lezignan), which is virtually unheard of in rugby league, so credit to all the lads on the pitch.”
However, Peter Lupton is still another week away from returning to first team action.
Town suffered a 22-6 defeat in last week’s Carnegie Challenge Cup clash with Batley, but joint coach Gary Charlton will not be using that as an excuse on Sunday.
He said: “We’ve got to dust ourselves down and train well.
“It’s going to be a tough game against London, but I expect a good performance resulting in three points.”
Skolars’ coach Joe Mbu has praised his side’s “determination” following their 43-26 defeat against Leigh.
