Slayton (hamstring) doesn't have an injury designation for Sunday's game at Detroit, Dan Salomone of the Giants' official site reports.
Slayton returned to practice Thursday as a limited participant and apparently didn't need long to prove his readiness. He'll jump back in as a starter after a one-game absence, now catching passes from Jameis Winston instead of Jaxson Dart, who will miss a second straight game due to a concussion.
