England batsman Kevin Pietersen is returning home on Tuesday after failing to recover from a rib injury."Scans taken after the first one-day match showed no fracture but demonstrated a stress lesion and despite passing a fitness test ahead of the second one-day match Kevin suffered intolerable pain throughout," England doctor Peter Gregory said in a statement. He also said that an injury such as Pietersen's normally required four to six weeks rest. "It is expected that Kevin will make a full recovery in time for the tour to India in March next year," he said.Pietersen said he was disappointed to be leaving the tour with the ODI series level at 1-1. I was looking forward to a strong series," he said. "I hate missing matches and despite trying to play the first couple of one-day games the pain was just too great.” (Reuters)
