Mark Wilson and joe Cokanasiga have emerged since doubts for the start of England’s World Cup campaign due to knee issues.
Cokanasiga and Wilson are unable to share in training in the squad’s camp at Miyazaki due to the injuries and, based on Eddie Jones, they are presently undergoing a”miniature”.
Both players were included in the last warm-up Test against Italy, Wilson starting at openside flanker and wing Cokanasiga making a second-half look from the bench.
But a question mark hovers over their participation in the Japan 2019 opener against Tonga in Sapporo on September 22 and potentially the second Pool C clash with the USA four days.
“When men get knocks and niggles they undergo a rehabilitation process according to a particular injury,” said defence trainer John Mitchell, who declined to reveal whether the players could recover in time.
England is going to be expected to sweep Tonga not after the Pacific Islanders were overwhelmed New Zealand recently.
However, the underdogs have a reputation for their ferocious tackling that could keep the medics busy in the time of a week.
“The Tongans are a very hard-working folks,” explained Mitchell. “They are obviously very passionate if they do play for Tonga.
“They are representing not only themselves and their family, but in addition a small island that’s produced a lot of rather good baseball players.
“It is going to be quite a special occasion for them. It’s something which will lift them.”
England input the ninth instalment of the World Cup as favorites along with hooker Jamie George and also South Africa understands the culmination of the Jones era has arrived.
“Eddie’s not giving us a lot of messages now we are here because the message was drilled into us for the last four years,” said George.
“When he first came in he said to us that we’re here to win the World Cup in four years’ time. We are in that area today.
“We are in a fantastic place to head outside and do this. We have got an awful lot of hard work to do to get there, so we’re not thinking too far ahead.”
