England full-back Mike Brown is in contention to return from having his Six Nations campaign curtailed by concussion after being retained in the training squad ahead of the visit of Scotland.
Brown was knocked unconscious during the 47-14 win over Italy and missed the loss to holders Ireland after failing stage three of the return to play concussion protocol – a process all players must undergo after suffering head injuries.
But ahead of the resumption of England's Six Nations campaign against Scotland on 14 March at Twickenham, Brown is back in contention to play after remaining with the squad this week. The Harlequins back is expect to resume training on 6 March.
Alex Goode, who stood in for Brown during England's 19-9 defeat at the hands of Ireland at the Aviva Stadium, has returned to Saracens and could face London Wasps in the Premiership clash on 8 March with his participation in the remainder of the Six Nations uncertain.
Joe Launchbury, Ed Slater and Manu Tuilagi remain with the squad as they continue to recover from respective neck, knee and groin injuries, with the trio running out of time to be involved in the final two championship matches. Luther Burrell will also sit out training due to a calf problem.
Of the 16 players who will train with England this week, Brown and centre Billy Twelvetrees are the only two players who did not start the defeat to Ireland, an indication head coach Stuart Lancaster may rework his backline should further injuries occur rather than call in Goode.
Victory against winless Scotland will keep the pressure on favourites Ireland going into the final weekend of the tournament but Lancaster warns his side must learn from their mistakes.
"[In the post-match press conference] I said some of the problems were of our own making," Lancaster said. "That is definitely still my opinion now.
"Our discipline – going into half-time with a penalty count of eight-four against us – and not taking our opportunity when we did go to the corner certainly had a bearing on the score.
"Then them scoring a try off the back of advantage from a penalty left us with a big hurdle to climb. We came back and there were some key moments with around 10 minutes to go when we had a try disallowed and were free-kicked at a scrum. But you have to be able to control the big moments at the time. I felt we didn't do that enough."
