The Bears have ruled EDGE Khalil Mack (foot) out for Monday night's game against the Steelers, the 2nd straight game he will have missed. LB Alec Ogletree (knee) is questionable and S Eddie Jackson (hamstring) is doubtful. Ogletree missed practice all week and doesn't look like a good bet. If he sits, Danny Trevathan would get the start in his place. Jackson's expected absence makes DeAndre Houston-Carson a good IDP option.
