Slayton (hamstring) didn't practice Wednesday, Jordan Raanan of ESPN.com reports.
Slayton and Sterling Shepard, both dealing with hamstring injuries, were at least able to do side-field work during Wednesday's practice, perhaps taking a step forward in the recovery process. Still, they're both in danger of missing a second straight game Sunday against the Cowboys, potentially giving Kadarius Toney and John Ross another shot to strut their stuff in top-three roles.
