The Rams designated Shelton (ankle) to return from injured reserve Wednesday.
Shelton has been on IR since suffering a high-ankle sprain during the team's Week 4 loss to the 49ers, but he'll return to practice Wednesday. With the move, the Rams open a 21-day window for the center to be added to the active roster, but if he isn't, he'll revert to IR for the remainder of the campaign.
