England's troubled build-up to the World Cup continued with the news that Anthony Watson will miss the entire tournament because of a calf problem.In the week Owen Farrell and Billy Vunipola were issued with bans that rule them out of the critical opener against Argentina, Steve Borthwick has now lost a first choice wing.Watson sustained the damage in Saturday’s 29-10 defeat to Ireland and has been replaced in the 33-man World Cup squad by Jonny May, who starts Saturday’s clash with Fiji.It is a savage blow for the 29-year-old who had previously battled back from long-term knee and Achilles injuries and was poised to start the Pumas showdown on 9 September."In the game against Ireland, Anthony Watson suffered an injury to his calf which means he can't play for a number of weeks," Borthwick said."As such he will not be part of the 33 that travels to France next week.
We’re all really disappointed for him."Watson follows ankle injury-victim Jack van Poortvliet in being forced to withdraw from the original squad named by Borthwick.Earlier on Thursday, reports emerged that England would also lose versatile back Elliot Daly to a knee injury, although Borthwick does expect him to be available for the start of the World Cup, along with Henry Arundell who is troubled by a back issue.Courtney Lawes will win his 100th cap when he captains England in Saturday's final warm-up match.With Farrell serving a four-match ban for a dangerous tackle, Lawes continues as skipper to become the fifth England player to amass a century of Test appearances, having made his debut in 2009.George Ford continues as chief conductor in a new-look half-back combination that includes Alex Mitchell, while Manu Tuilagi and Ollie Lawrence are paired together
