Bell (ankle) was listed as a non-participant on Monday's practice estimation, Nick Harris of the Fort Worth Star-Telegram reports.
According to Harris, head coach Mike McCarthy told reporters Monday that the team will "know more tomorrow" about Bell's ankle injury after being estimated as DNP. The 25-year-old didn't return to Sunday's loss to the Ravens after sustaining the ankle injury, and if he's unable to suit up Thursday night against the Giants, expect Juanyeh Thomas to see increased playing time as the Cowboys' top backup safety.
