Carolina Panthers linebacker Dan Morgan is sitting out one more game.

Morgan won't play when the Panthers meet the New Orleans Saints in Charlotte on Sunday. He hasn't played since suffering at least the fifth concussion of his career in the season opener against Atlanta. Coach John Fox says there's no target date for Morgan's return.

Tight end Mike Seidman will also miss the game against the Saints after suffering a knee injury in last Sunday's win over Tampa Bay.

The Panthers also remain banged up on the offensive line. Center Justin Hartwig, who's missed the past two games with a groin injury, didn't practice today and is listed as questionable. Tackle Todd Fordham also missed practice and is questionable with a shoulder injury.

Safety Shaun Williams rode a stationary bike and did some agility drills. He missed the Tampa Bay game with a right foot injury and also is questionable for the New Orleans game.
