England number eight Phil Dowson is still in the running for this weekend's Six Nations clash against Ireland despite being knocked out in the closing stages of last weekend's 24-22 victory over France.
The Northampton number eight has been retained in a 24-man England training squad ahead of the tournament finale in Twickenham, with England's interim coach Stuart Lancaster to confirm the final team on Thursday.
Lancaster has included both David Strettle, who missed the France game with a chest injury, and his replacement, Charlie Sharples.
As a result, Harlequins scrum-half Karl Dickson is one of eight players released back to their clubs this weekend, including Leicester fly-half Toby Flood.
