Tre'Quan Smith's continued injury absence puts himself and Saints in a tough spot

"For what it’s worth, ESPN’s broadcast team reported that Smith is managing a hamstring injury during the Saints-Jaguars matchup.

Smith could very well return to practice tomorrow and not miss a beat until the Sept. 12 season opener against Green Bay. But that just feels too optimistic given how much time he’s spent out of action so far."

This would explain the caution. Rest is what's best for a hamstring. Smith and Winston worked out together all Summer long so they shouldn't have an issue with timing.
