SAN DIEGO -- Two potential starters on the defensive side of the ball returned to practice for the San Diego Chargers on Monday, a signal the duo could play in the team’s season opener against the Arizona Cardinals.

Inside linebacker Manti Te'o missed the last two preseason games with a sprained left foot, but worked with his position group during the early portion of practice on Monday.

Starting defensive tackle Sean Lissemore, who has not played or practiced since suffering a right ankle injury against the Seattle Seahawks in the second preseason game on a cut block by tight end Zach Miller, also was on the practice field working with the defensive linemen.

Joining Lissemore was fellow defensive lineman Lawrence Guy, who had not practice since suffering a shoulder injury in the exhibition opener against the Dallas Cowboys.

Safety Jahleel Addae remains out with a hamstring injury. Cornerback Chris Davis and receiver Jevontee Herndon also did not practice due to unknown injuries.

The Chargers are not required to release an injury report until Wednesday.
