Pakistan seamer Ehsan Adil has been ruled out of the remainder of the ODI series against Bangladesh after sustaining a hamstring injury. Umar Gul, who had been omitted by the selectors for the ODIs, will join the team as his replacement. Adil is the fourth Pakistan player to be ruled out of the series after Sohaib Maqsood, Sohail Khan and Yasir Shah had pulled out due to injuries.It is understood that Adil picked up the injury during training ahead of the first ODI on Friday, which Pakistan lost by 79 runs, only their second loss to Bangladesh in ODIs. The bowler was expected to regain his fitness before the second match on Sunday, but has failed to do so.”It was expected that he would get fit ahead of the second ODI but his recovery didn’t go well,” Haroon Rashid, PCB’s chief selector, told ESPNcricinfo. “He has been called back and Umar Gul is being sent as an immediate replacement.”Adil, 22, made his international debut in February 2013 and has played two Tests and six ODIs since then. He played a couple of games in the World Cup, including the quarter-final against Australia, but did not have much success, managing two wickets for 62 runs in 12 overs.Umar Gul missed the World Cup after sustaining a bruised tendon in his left ankle following the first ODI against New Zealand in Dubai in December 2014. This will be his fourth comeback since the knee surgery that forced him out of action throughout 2013.
