Defensive tackle Corey Peters was activated by the Atlanta Falcons from the reserve/non-football injury list.
Peters suffered a stress fracture in his foot he suffered in the offseason working out with a trainer before the team's official program started. He returned to practice Monday, and the Falcons hope he can help improve their 28th-ranked run defense that is allowing 143.8 yards per game.
How much action Peters will see against the Philadelphia Eagles on Sunday remains to be seen, as coach Mike Smith acknowledged earlier this week that Peters isn't in football shape yet.
Peters was a third-round pick in 2010 who started 30 of 31 games over his first two seasons.
Cornerback Terrence Johnson was waived by the Falcons.
