Slayton suffered an ankle or foot injury during Sunday's preseason contest versus the Patriots, Art Stapleton of The Bergen Record reports.
Slayton had his left foot taped up during the first half of this game but was able to return. Now that he's questionable to get back on the field, though, he likely will end his day with one catch (on two targets) for six yards and one carry for seven yards. Because Slayton is the second key skill player to suffer an injury Sunday -- Evan Engram was ruled out with a calf issue -- the third-year wide receiver isn't a prime candidate to see action again until Week 1 against the Broncos.
