The 23-year-old limped off in the 81st minute of Tuesday's 2-0 Capital One Cup third-round victory over Sheffield Wednesday - his first match back from an ankle problem suffered in pre-season. Cork was seen at St Mary's in a leg brace on Thursday and has confirmed via his Twitter account that he faces another stretch on the sidelines.
"Another 4-6 weeks, with my left knee," he said on the social media site.
"Lucks just not going my way this season. Could be worse, but was so close to getting back from the ankle."
