Strong (hamstring) didn't practice Wednesday, Daniel Oyefusi of ESPN.com reports.
Browns head coach Kevin Stefanski said Monday that Strong is considered week-to-week after injuring his hamstring in Sunday's 18-13 win over Jacksonville. Strong thus is likely to miss at least one game, leaving Cleveland's backfield in the hands of Jerome Ford and D'Onta Foreman, both of whom had already been working ahead of Strong.
