George Ford has won his fitness battle after England declared him ready to face Ireland in Saturday's Autumn Nations Cup clash at Twickenham.

Ford missed the emphatic victories over Italy and Georgia that opened the end-of-year campaign because of a pre-existing Achilles injury but the Leicester fly-half has made a full recovery.

Head coach Eddie Jones names his team on Thursday morning with Ford pushing hard to either reclaim the playmaking duties from Owen Farrell, forcing England’s captain to move to inside centre, or supplying cover from the bench.

"George is looking good, he’s training really hard. It’s good to have his experience and adaptability in the squad. He’s been training really well," forwards coach Matt Proudfoot said.

A 25-man squad has been retained to finalise preparations for the visit of Andy Farrell’s team to Twickenham with one back and one forward to be jettisoned, unless Jones opts for a six-two split on the bench.

One missing face is Wasps flanker Jack Willis, who delivered an outstanding try-scoring debut against Georgia but has now been frozen out.

Overlooking a rookie who has performed well is a well-trodden path by Jones, who likes to deliver well-timed shots across the bows to keep his players hungry.

"We're very pleased with Jack, he’s done very well and is pushing hard and growing," Proudfoot said.

"We want him to be a better player week in, week out and we feel he’s doing that. He has a good appetite to learn and has a bright future ahead of him.

"He did well against Georgia, his first cap produced a try and he performed really well in tough conditions for a loose forward.

"He really had to dig deep and he did. It was great for a forward to put in a debut like that."

When asked about Willis’ omission, Proudfoot stated that selection is partly shaped by a detailed analysis of the opposition.

"You look at what you’ve got at your disposal. You look at the challenge. And then you pick the best 23," he said.

"Each guy has got to be pushed during training sessions to show that he’s in the best form and we’re looking at what the opposition presents us.

"The Irish forwards, especially the loose forwards, are very very good. CJ Stander, Peter O’Mahony, Josh Van Der Flier are unbelievable loose forwards.

"So we’re looking forward to meet that challenge, how best can we nullify that threat of theirs, and we select what we feel is the best team to counter that threat."

Andy Farrell has already named his Ireland team, with Leinster out-half Ross Byrne taking the place of injured captain Johnny Sexton, and Jamison Gibson-Park retaining the No 9 jersey ahead of Lion Conor Murray.
