England face nervy wait over Kruis
INJURY UPDATE: England lock George Kruis could be in doubt for England's Six Nations opener against France on Saturday after suffering a knee injury during training on Tuesday.
Kruis, who recently recovered from a fractured cheekbone, joins wing Anthony Watson (hamstring), Chris Robshaw (shoulder), Billy Vunipola (knee), Mako Vunipola (knee) and Manu Tuilagi (groin) on the injury list while loose forward James Haskell is struggling to overcome the lingering effects of a foot injury.
"George Kruis will go for further medical assessment tomorrow morning [Wednesday, February 1] to determine the extent of a knee injury picked up in training," read the statement from the Rugby Football Union (RFU).
England and coach Eddie Jones - who is defending a 13 match winning streak since taking over after the 2015 World Cup - have had their Six Nations preparations disrupted by a series of injuries to players.
England are on a 14-Test winning streak, 13 of those victories coming since Australian coach Eddie Jones took over after their 2015 World Cup debacle on home soil.
They are set to be captained once again by Dylan Hartley, who will play his first competitive fixture since he served a six-week ban for striking Leinster's Sean O'Brien.
In preparation for their Six Nations opener against France, Eddie Jones has retained 25 players for the Twickenham fixture.
