Leeds: England offspinner Graeme Swann has admitted he may need further surgery if problems with injuries persist. The 33-year-old confessed on Tuesday that his 'worst fear' is his troublesome right elbow which might keep him out of the second Test. "If it keeps deteriorating, I will undoubtedly have to miss some cricket. But it has not really deteriorated in the last three or four weeks â it feels better than it did. I'll have to cross that bridge when I come to it. I don't want to have another operation if I can help it because it's horrendous. That is my worst fear at the minute,â said Swann. Swann was given a fortnight's rest and a cortisone injection in his elbow before the first Test against South Africa at The Oval. He already had one major operation on the elbow, in Connecticut before the 2009 Ashes series. The surgeon removed 26 pieces of floating bone but had to leave three because they were too close to a nerve. "There are bits of floating bone in there. He said they may cause a bit of grief now and then. It is little things, like if I hold the phone too long with my right hand I can't use my arm for a couple of minutes â it just goes dead,â said Swann. If Swann makes the cut for Headingley Test, it will be his 44th consecutive Test.
