Browns outside linebacker Barkevious Mingo is scheduled to undergo arthroscopic knee surgery Thursday to repair a torn meniscus, a source familiar with the situation told the Beacon Journal.
The source spoke on condition of anonymity because the Browns have yet to announce the surgery would take place.
The timetable for Mingo's return is expected to be three to four weeks, the source said.
The injury occurred in a recent practice, the source said.
