Mike Brown could be back for England's Calcutta Cup clash against Scotland after it was revealed he should be back in training by Friday.
The Harlequins full-back was forced to miss the 19-9 defeat in Ireland after suffering a concussion in the win over Italy a fortnight ago.
According to Stuart Lancaster, he is on course to return to training by the end of the week, and could feature against the Scots if he passes all the return to play protocols.
However, while that was good news for England, they will be without Luther Burrell in training tomorrow at least, with the Northampton centre suffering from a calf problem.
"We reviewed the game as a whole squad and trained this afternoon," said Lancaster.
"Luther Burrell has a calf strain and will not train tomorrow. Mike Brown has progressed well and we hope to have him back in full training on Friday.
"The majority of the bench players and non-match day 23 will be released back to their clubs over the next 24 hours and be available for this weekend’s Premiership games.
"We feel they will benefit from some game time and the chance to put themselves in contention for the Scotland match and we will give an update on those players tomorrow."
