Smith didn't practice Wednesday due to an ankle injury, Erik Bacharach of The Tennessean reports.
Smith logged 54 of the Titans' 62 offensive snaps in the team's Week 2 win over the Jaguars, finishing with four receptions for 84 yards and two scores on five targets. He wasn't reported to have suffered an injury during the game, so it's possible his practice reps are simply being managed to start the week. Smith's return to the field Thursday -- in any capacity -- would support that notion and put him on track to serve as Tennessee's top tight end Sunday against the Vikings.
