Report: 49ers' Reuben Foster dealing with high ankle sprain

San Francisco 49ers linebacker Reuben Foster suffered a high ankle sprain in Sunday's loss to the Carolina Panthers, sources told Ian Rapoport of NFL Network.

Rapoport adds that Foster will undergo more tests and is expected to miss time.

Foster was carted off the field after going down with the injury but returned to the sidelines shortly after. After the contest, X-rays on the ankle came back negative and Foster seemed confident he'd suit up in Week 2.

Reuben Foster says he thinks he'll play next week in Seattle. He said he wanted to return to today's game in the second half.

That may be difficult to do with a high ankle sprain, but at least the 49ers can take solace in the fact that their star rookie doesn't appear to be out long term.
