Coach Dan Quinn would not confirm on Friday the linebackers will return as starters, the roles they held before their injuries. Campbell (ankle) and Jones (ankle) missed last week's win at Denver .
Quinn says backup linebacker Paul Worrilow (groin) will not play this week.
The injuries at linebacker came at the same time veteran Sean Weatherspoon was placed on injured reserve with an Achilles tendon injury.
The Falcons signed veteran A.J. Hawk for depth and also had help from strong safety Kemal Ishmael.
Receiver Julio Jones, who had been limited by knee soreness this week, had full participation in Friday's practice.
