Linebacker Sean Weatherspoon and cornerback Asante Samuel have returned to practice in a limited role on Friday for the Atlanta Falcons.
Another defensive starter, nose tackle Peria Jerry, misses his third straight practice with a quadriceps injury.
All three players are listed as questionable for Sunday's game at Tampa Bay (6-4).
The Falcons (9-1) list reserve defensive tackle Vance Walker (ribs) as questionable.
A right ankle sprain has sidelined Weatherspoon for the last three games. He returned to practice on Wednesday, but missed Thursday's session with an undisclosed illness.
Samuel is nursing a sore shoulder. He and Jerry were injured in last week's home win over Arizona.
Two other defensive starters, right end John Abraham and Jonathan Babineaux, are listed as probable after fully participating on Friday.
