Slayton was forced out of Sunday's game against the Falcons in the first quarter with a hamstring injury, Zack Rosenblatt of The Newark Star-Ledger reports.
With Slayton having been declared done for the day, he'll finish up with one catch for eight yards. In his absence, Kenny Golladay and Sterling Shepard will continue to head the Giants' Week 3 WR corps versus Atlanta.
