Rio de Janeiro, Aug 28 : Sao Paulo vice captain Dani Alves has undergone surgery to repair the broken right forearm, the Brazilian Serie A club has said. The 37-year-old suffered the injury in the second half of his team's 1-0 home victory over Athletico Paranaense on Wednesday, a result that left Sao Paulo third in the 20-team league standings. "We cannot forecast the recuperation period but we hope it will be (short) because it is an aligned fracture with a good recovery prognosis," club doctor Jose Sanchez said in a statement on Sao Paulo's official website on Thursday, reports Xinhua news agency. Alves joined Sao Paulo as a free agent last July after his contract expired with Paris Saint-Germain. The defender-turned-midfielder has been capped 118 times for Brazil and is the most decorated professional footballer in history with 43 trophies over a career spanning two decades. /IANS
