Brightwell won't play in Sunday's preseason matchup against the Bengals, Pat Leonard of the New York Daily News reports.
Both Brightwell and Matt Breida (undisclosed) will be held out against Cincinnati, so Antonio Williams and Jashaun Corbin should have increased opportunities in the Giants' backfield. Brightwell will try to return for the team's final game of the preseason Aug. 28 against the Jets.
