Coach Mike Vrabel hopes that Mariota (stinger) can practice Thursday, Jim Wyatt of the Titans' official site reports.
Mariota didn't practice Wednesday, instead undergoing treatment related to the stinger he suffered in Week 16. His status for Sunday's win-or-go-home contest against the Colts won't be clarified until later this week, but the quarterback previously stated that he intends to give do whatever he can to give it a go. In Mariota's absence at practice, Blaine Gabbert handled first-team reps.
