Panthers promote two from the practice squad for opener

Teams can promote up to two players from the practice squad each week, and they automatically revert to the practice squad following the game. Individual players can be elevated up to three times before they’d have to be signed to the 53-man roster to appear in another game.

Moon adds depth at outside linebacker, where the Panthers have already ruled out Patrick Jones II because of a back injury, after losing Nic Scourton during training camp to a season-ending knee injury.

Simmons is one of the team’s top special teams players, who was caught in a numbers game when the team kept three quarterbacks and five tight ends on the opening-week roster.
