Owen Farrell has become a doubt for England’s Guinness Six Nations after suffering a new injury in training for his club Saracens.

It was hoped Farrell would make his comeback after a two-month absence because of ankle surgery in Sunday’s Challenge Cup clash with London Irish in Barnet.

But England’s skipper has been ruled out by a fresh setback and the Rugby Football Union has revealed that he will not be attending next week’s pre-Six Nations training camp in Brighton when a captaincy update will be issued.

The 30-year-old was set to start at inside centre in the opener against Scotland at Murrayfield on February 5, but this development would appear to end any hope of being involved.

And his participation in the rest of the tournament hinges on the severity of the new injury, the nature of which has not been specified.

“Owen Farrell suffered an injury in training this week ahead of the game against London Irish, ruling him out of the match,” a Saracens statement read.

“Owen was back in full training having recovered from the ankle injury he sustained against Australia during the autumn internationals. We will have a further update after he sees a specialist early next week.”

Eddie Jones took the unusual step of appointing Farrell as skipper for the whole Six Nations as early as Tuesday’s squad announcement, but the head coach is now having to revise his plans.

Even if scans reveal the injury is minor, his inability to play against London Irish and absence from the first training camp of the year would appear to rule him out of the trip to Edinburgh.

He has not played since hobbling off against the Wallabies on November 13 – his 100th cap including Lions appearances – and Saracens are currently looking after his recovery.

England will name any adjustments to their 36-man squad on Monday with Henry Slade, Mark Atkinson, Joe Marchant and Luke Northmore the fit centres who will gather in Brighton.

Slade was magnificent during the autumn and could be shifted from 13 to 12 with either Marchant or Northmore slotting in outside him. Another option would be Atkinson and Slade forming a midfield partnership with Marcus Smith set to pull the strings at fly-half.
