George Kruis could miss England's Six Nations opener against France
The Saracens second row will be assessed further today but Eddie Jones's plans to pair him with Courtney Lawes at Twickenham could be compromised.
With Maro Itoje set to start his first Test in the back row, Joe Launchbury is the alternative to Kruis who was on target to make his return from a broken cheekbone sustained on club duty on December 23.

Another long-term absentee, James Haskell, is also poised to make his England comeback after he missed the autumn internationals with a troublesome toe injury.
Haskell sat out the first part of England's pre-championship training camp in Portugal with a recurrence but was retained in a trimmed-down 25-man squad last night and is likely to make the final 23 – most probably on the bench.

England also suffered complications with their wings yesterday with Jonny May needing stitches above his eye after a clash of heads and Jack Nowell missing training.
