The high-flying Magpies have drawn four of their last five Premier League games.
Harry McKirdy and Joe Newell were the latest to sustain injuries on Saturday.
England head coach Steve Borthwick said his side must endure some “pain” in order to grow, following a gut-wrenching Six Nations loss to Scotland at Twickenham. Duhan van der Merwe inspired the Scots to a dramatic victory which saw them retain the Calcutta Cup with a 29-23 bonus-point win. “We’ll have a good look at it and I think this is part of the growth of the team, you have to go through some pain,” Borthwick said.
