Kelechi Iheanacho is doubtful for Nigeria&rsquo;s final African Cup of Nations qualifying fixture against Tanzania in Uyo next weekend after picking up an injury in Manchester City&rsquo;s Champions League game with Steaua Bucharest on Wednesday night.<br /><br />In his first start under manager Pep Guardiola, the Nigeria international was stretchered off in the 76th minute after picking up what appears to be a muscle injury. <br /><br />The 19-year-old Iheanacho pulled up chasing a ball through and City medical staff arrived quickly to attend to him. <br /><br />The attacker will undergo tests in the coming days to determine the severity of his injury and how long he will have to spend in the treatment room. <br /><br />Nigerian defender Tosin Adarabioyo appeared off the bench for City on the hour mark, his first appearance in the Champions League. <br /><br />Man City qualified 6-0 on aggregate and will find out their opponents in the group stage on Thursday.<br /><br />Ifeanyi Emmanuel <br /><br />Photo Credit : mancity.com <br />
