The Giants released Slayton on Monday, Matt Zenitz of CBS Sports reports.
In the wake of Slayton getting cut, New York boasts a receiving corps led by Malik Nabers (knee) and supplemented by Darnell Mooney, Malachi Fields and Odell Beckham. Considering the group is only four deep ahead of Week 1, it wouldn't be a surprise if Monday's move is merely procedural, and Slayton could be back on the Giants' practice squad, from which he would be allowed to get elevated a maximum of three times on game days.
