Tillery left Saturday's practice session on a cart due to a lower right leg injury, Mark Craig of the Minneapolis Star Tribune reports.
Tillery signed a one-year deal with the Vikings in March after spending the last two years with the Raiders, and the 2019 first-round pick is slated to start at defensive end opposite Jonathan Bullard. If Tillery were to miss extended time, Jonah Williams and Jihad Ward are candidates to see more snaps with the first-team defense during training camp and preseason games.
