Warren (groin) was not present for Thursday's practice, Kevin Bowen of 107.5 The Fan Indianapolis reports.
Warren looks to be sitting out a second consecutive practice due to a groin injury, which also kept him out of the Colts' loss to the Titans this past Sunday. Will Mallory drew six targets in Warren's absence, and Mallory could continue to play an elevated role Sunday against the Vikings if Warren is ruled out. Warren will have one more chance to practice in some capacity Friday.
