The NFL has upheld Lions DT Ndamukong Suh's two-game suspension for violating the league's on-field conduct policy after an appeal attempt. Suh will sit out Sunday's game against the Saints and next week's home game versus the Vikings. The Lions should be pleased if they emerge from the two-game stretch 1-1. Heading into the New Orleans game, Detroit should be quite concerned with its pass defense. Suh won't be rushing quarterbacks and drawing double teams, and CB Chris Houston (knee) and FS Louis Delmas (knee) both missed practice all week. Drew Brees could shred them in Week 13.
