Slayton underwent X-rays on his thumb following Sunday's 21-15 win over the Browns, but they came back negative, Jeremy Fowler of ESPN.com reports.
Slayton was briefly forced out of Sunday's contest early in the fourth quarter due to the thumb injury, but he returned with 7:40 remaining and finished the afternoon with a 1-7-0 receiving line on two targets while logging 81 percent of snaps. The wideout might have been playing through some discomfort the rest of the game, but with X-rays coming back negative, Slayton would seem to have a good chance at being available for the Giants' Week 4 matchup with the Cowboys on Thursday night.
