Wilson is not expected to require surgery to repair his hyperextended left knee, Jeremy Fowler of ESPN.com reports.
Wilson could carry a four- to six-week recovery timetable if he's indeed able to avoid surgery, through previous reports had him pegged to miss at least six weeks. If it looks as though the second-year linebacker is on track for the latter end of that recovery timeframe, the Browns could realistically opt to place him on the PUP list to start the season.
