( CNN ) -- Liverpool captain Steven Gerrard has had an operation on his groin and will be out of action for four weeks , the English Premier League club confirmed on Friday . The England midfielder is thought to have sustained the injury during the February 6 victory at Chelsea , although he continued to play for the club until Sunday 's 3-1 win over league leaders Manchester United . However , Gerrard did not travel to Portugal for Thursday 's 1-0 defeat at Braga and will now miss the return leg of the Europa League last-16 tie at Anfield on March 17 . `` Gerrard has undergone successful surgery on his groin and will be out for up to four weeks . The decision was made following consultation with a specialist , '' said a statement on Liverpool 's official website . The 30-year-old will now miss at least three Premier League games , including upcoming trips to Sunderland and West Brom plus a home game against Manchester City . With Liverpool lying in sixth position in the table , the best manager Kenny Dalglish can hope for is that his skipper will have recovered in time for the club 's last six league matches this season . Gerrard has also been ruled out of England 's Euro 2012 qualifying match against Wales on March 26 , as well as a friendly against Ghana . United will be without Nani for Saturday 's FA Cup quarterfinal against Arsenal , with the influential Portugal winger expected to be sidelined for about three weeks after requiring stitches in the leg injury he suffered against Liverpool . `` We have managed to stitch it , which is great news , '' United manager Alex Ferguson told reporters . `` What we are guarding against is infection , but the swelling has gone down a great deal . `` It is very difficult to say when he will be back but we do have a two-week break after next Saturday . He will be ready for the return of that , that 's for sure . '' England defender Rio Ferdinand and midfielder Park Ji-Sung remain sidelined , but Serbia center-back Nemanja Vidic returns from suspension as Ferguson prepares for first Arsenal and then Tuesday 's second leg of the Champions League last-16 tie at home to Marseille .
