Giants head coach Brian Daboll said that Slayton (concussion) won't participate in practice Wednesday, Connor Hughes of SNY.tv reports.
Slayton remains in the NFL's concussion protocol and will likely need to get back on the practice field in some capacity in addition to gaining clearance from an independent neurologist to have a chance at playing Sunday against the Commanders. Jalin Hyatt will have a path to increased offensive snaps alongside starting wideout Malik Nabers and Wan'Dale Robinson if Slayton misses any time.
