Slayton (concussion) practiced in full Wednesday, Dan Salomone of the Giants' official site reports.
Slayton made a late departure from a Week 9 loss to the Commanders and subsequently was placed in the concussion protocol. He wasn't able to gain clearance from an independent neurologist in time to travel with the Giants to Germany for a Week 10 matchup with the Panthers, but following the team's bye, he wasn't inhibited in the first session of Week 12 prep. It's unclear if Slayton is out of the concussion protocol, but Wednesday's uncapped practice bodes well for his chances of playing Sunday against the Buccaneers.
