Bears OLB Khalil Mack (foot) is questionable for Sunday's game at Tampa Bay. He has made a habit of playing through questionable tags, so it seems unwise to bet against Mack. The Buccaneers present 1 of the league's worst sack matchups, though. So it's not a great spot for an active Mack. Also questionable are DL Akiem Hicks (groin), DL Bilal Nichols (knee) and CB Duke Shelley (ankle). Chicago has ruled out S Tashaun Gipson. Deon Bush, who replaced an injured Gipson earlier this season, is on IR. So it'll be DeAndre Houston-Carson starting in Gipson's place.
