Folk missed practice Wednesday due to a groin issue, Jim Wyatt of the Titans' official site reports.
Folk made both of his field goal-attempts in this past Sunday's 10-6 loss to the Jaguars, but he may have tweaked his groin at some point during the contest. The Titans haven't disclosed the severity of Folk's injury, but it's worth noting that Tennessee signed kicker Brayden Narveson to their practice squad Wednesday, per Wyatt. If Folk ends up missing Sunday's matchup against the Bengals, Narveson would presumably be elevated to take over as the team's placekicker.
