They also will have nickelback Drew Coleman available against the Steelers.
Smith and Coleman passed post-concussion tests this week and were cleared to play. The team also gave Kampman the green light after missing the past 13 games because of a knee injury.
Coach Jack Del Rio says Kampman will be available for 15 to 20 snaps.
Left tackle Eugene Monroe is questionable because of a shoulder injury. Monroe re-aggravated the injury last week. He is expected to be available, but not in the starting lineup.
