The Eagles have secured only two wins this year – against Gateshead in early February and against Leeds Met last week – but coach Mark Aston will be confident his team are now prepared for the week-to-week rigours of the Championship.
Betts said: “I’m pleased for Danny because it’s been a long, hard road for him. He’s worked hard and really dedicated himself to getting back out on the field.
“When he first came down here, I was really impressed with his attitude. He was really knocked for six and he’s come back from a very, very tough situation, so I’m genuinely pleased for him.”
Sculthorpe could feature again along with Chaz I’Anson – “the physio is pleased with how both of them have reacted,” said Betts – when Widnes finalise their team for Sunday’s trip to Bramall Lane.
Betts said: “Sunday will be a tough day. Mark Aston will have his team fired up and they’ll be very tough opposition.
“Mark doesn’t waste time with pre-season games. He uses the Northern Rail Cup games to get his side ready to go, and that’s what we’ve got to be prepared for on Sunday.”
