In addition, the Flyers recalled defenseman T.J. Brennan and goaltender Alex Lyon to fill their respective roster spots. Both players are in Edmonton and will be available for Wednesday's game against the Oilers.
Defenseman Mark Alt is expected to take Manning's spot in the lineup and will likely be paired with Travis Sanheim. Lyon will serve as the backup to Brian Elliott, who has started 10 of the Flyers' last 12 games.
Manning is eligible to come off IR on Dec. 13 and play the next night against the Buffalo Sabres. Neuvirth can be activated at any time since the move is retroactive to his last appearance - Nov. 28 against the San Jose Sharks.
