Slayton (hamstring) didn't participate in Thursday's practice, Dan Duggan of The Athletic reports.
According to Zack Rosenblatt of The Newark Star-Ledger, both Slayton and Sterling Shepard (hamstring) were at the Giants' practice facility Thursday, but head coach Joe Judge suggested that both wideouts would merely work with trainers behind the scenes. With neither receiver having taken any reps through the first two practices of the week, both appear to be trending in the wrong direction for Sunday's game in New Orleans. If Slayton is in fact sidelined this weekend, Collin Johnson and C.J. Board look like the main candidates to replace him at the boundary receiver spot opposite Kenny Golladay, though the Giants could also bring back John Ross (hamstring) from injured reserve in advance of the contest.
