Slayton (hamstring) has been ruled out for Sunday's game against the Cowboys, Jordan Raanan of ESPN.com reports.
The same goes for Sterling Shepard, whose absence has freed up slot work for first-round pick Kadarius Toney. Slayton's missing perimeter snaps have mostly gone to a mix of John Ross, Collin Johnson and C.J. Board, with Ross coming on strong last week to put up 3-78-1 in his first game back from IR. In any case, Slayton and Shepard will shoot for a Week 6 return against the Rams.
