Northampton forward Calum Clark has been recalled to the England squad for the RBS 6 Nations after serving a 32-week ban for breaking the elbow of an opponent.
Clark, who was on the fringes of the national team this time last year, is one of two uncapped players in the 33-man squad along with Gloucester centre Billy Twelvetrees. Joe Launchbury, Tom Youngs, Mako Vunipola and Freddie Burns have all been formally promoted into the senior squad after impressing during England's autumn international campaign.
England's search for a left wing has led to a return for David Strettle in place of Charlie Sharples, who is more at home on the right, and James Haskell has replaced Phil Dowson in the back row.
Youngs has taken the place of injured Bath hooker Rob Webber, Launchbury has ousted Wasps team-mate Tom Palmer and Vunipola is an additional selection in an expanded 33-man squad.
Head coach Stuart Lancaster has dropped centres Anthony Allen and Jordan Turner-Hall for Burns and Twelvetrees. Clark has been preferred to Mouritz Botha. The combative 23-year-old gives England options in both the back row and second row, offering the same versatility as his Northampton colleague Courtney Lawes.
Lancaster has been a long-time admirer of Clark's ability and he selected the Leeds academy graduate for last year's Six Nations squad. But Clark's career was put on hold in March, when he pleaded guilty to breaking the elbow of Leicester hooker Rob Hawkins in the LV= Cup final.
Lancaster said: "He has had a tough lesson to learn and he has learned it. I have watched his games closely, the first one being against Leicester. He has been harnessing the competitive nature he has got, which you want in players to win games, but he is channelling that in the right way.
"He has had tough lessons to learn. I have coached him since he was 14, I probably know him better than most. I know what he can offer. In addition to his desire to win, his versatility in the second row is an option for us. He is incredibly athletic and very good in the contact areas."
