Smith (foot) was a limited participant at practice Monday, Adam Caplan of SiriusXM Radio reports.
Smith missed the Saints' Week 12 win over the Falcons with the foot injury but his presence at practice to start the week is a promising sign. The 22-year-old began preparations for last week's game as a non-participant in practice, so he's seemingly in better shape this time around. That being said, Smith's involvement in practice sessions Tuesday and Wednesday will provide more insight into his chances of playing Thursday against the Cowboys.
