New Orleans, LA -- (Sports Network) - The New Orleans Saints placed tight end Mark Campbell and running back Aaron Stecker on the injured reserve list Wednesday, effectively ending each player's season.

Campbell, a 10-year veteran out of Michigan, caught 12 passes for 121 yards and two scores in nine contests before suffering an injury to his left knee in Sunday's victory at Kansas City.

Stecker has played through a lingering hamstring injury for most of the season, logging just 43 yards on eight carries in six games. The nine-year veteran is one of the club's five season-long captains.

To fill their spots on the roster, the Saints signed free agent running backs Darian Barnes and Mike Bell, who is two years removed from rushing for 677 yards on 157 carries for the Denver Broncos in his rookie campaign.
