The shoulder injury that forced Darren off after just ten minutes tonight is expected to keep the midfielder out for 2 months
Swansea City midfielder Pratley fell awkwardly early on in the Swans 4-1 win over Preston at the Liberty and was immediately replaced by Guillem Bauza.
And early diagnosis suggests that he could be out for up to eight weeks with Roberto telling BBC Sport "We think it's the joint, but we need to get the X-rays from the hospital
"We've lost players in the past... We knew we had to have a squad capable of dealing with those situations."
Further news is expected on Wednesday
