The Carolina Panthers took a cautious approach with a couple of their key injured players against the New Orleans Saints on Sunday with an eye on having them healthy for the stretch run. Tight end Greg Olsen was held out after aggravating his surgically repaired foot in the 31-21 loss in New Orleans, and outside linebacker Thomas played only 39 percent of the defensive snaps because of a hamstring issue.

The team didn’t want him to suffer another setback that might have sidelined him the rest of the season.

It’s tough on the body. It’s tough on the feet, the ankles, the knees, the joints,” Rivera said. “We’ll see. Hopefully we can pick a couple of those guys back up and we’ll go from there.” Davis, 34, played a season-low 25 snaps (out of a possible 64) and finished with two tackles, which tied for his season-low. Rivera said the Panthers didn’t want to overdo it with their longest-tenured player. “We were trying to be very aware of that,” Rivera said. “TD’s an explosive player. He made some plays for us and unfortunately we
