Pakistan spearhead Sohail Khan was Sunday ruled out of the tour of Bangladesh after suffering a back injury and was replaced by Junaid Khan.This is the second injury setback for Pakistan after batsman Sohaib Maqsood was also ruled out last week due to a fractured arm.

Sohail, 31, suffered the injury on the last day of team's training session in Lahore after breaking down in his fourth over of a practise match. Pakistan Cricket Board (PCB) said Sohail was advised to rest for two to three weeks. "Sohail suffered a back injury at the training camp, precisely reporting pain during the practice match, and post MRI scan he was advised recuperation for 2-3 weeks," a PCB release said.

Sohail staged a surprise comeback after a four-year hiatus and impressed with his five-wicket in the key match against India in the World Cup held in Australia and New Zealand in February-March.

Pakistan will open the tour with the first of three one-day internationals in Dhaka on Friday. They also play a Twenty20 and two Tests on the tour.
