Bell (quadriceps) did not practice Monday, Mary Kay Cabot of The Cleveland Plain Dealer reports.
Bell has been out of action since suffering the injury Aug. 10 against the Packers. The third-year pro was expected to return to practice this week, but for now, he'll be considered questionable for Cleveland's Week 1 matchup with the Cowboys on Sunday. Currently slotted in as the team's No. 5 wideout on the positional depth chart, his potential absence likely won't have much of an impact on the offense but would probably allow rookie Jamari Thrash to see a few snaps.
