Ricci reverted to the Lions' practice squad Monday, per the NFL's transaction log.
Ricci played 24 snaps (14 on offense, 10 on special teams) during the Lions' 29-24 loss to the Steelers on Sunday, but he did not show up on the box score otherwise. He's been elevated from the practice squad twice this season, and he's eligible to be called up once more over the final two games of the regular season.
