Chelsea captain John Terry is hoping to be back playing within a month after undergoing knee surgery. The 31-year-old defender played through the pain after initially suffering the problem at the start of last month, but went under the knife last week. He told The Sun: \"The operation went well and I\'m feeling really good. The surgeon has shaved off a bit of bone in my right knee that was rubbing and causing a lot of swelling. \"We\'re all confident the operation has solved the problem and it is looking good for a quick return. The medical staff say four to six weeks before I can play again. But, hopefully, it might be sooner. \"I\'ll definitely be back before the end of the season to help the team in the Premier League run-in and for the Euros.\"
