Smith (knee) was a limited practice participant Thursday, Dan Salomone of the Giants' official site reports.
Smith's knee injury popped up this week, leaving all the Giants' TEs with health concerns in advance of Week 1. With Evan Engram yet to practice due to a calf injury he sustained in the exhibition finale, the team maybe forced to roll with Smith and Kyle Rudolph (foot) -- who has been limited all week like Smith -- at tight end Sunday versus the Broncos.
