Titans QB Marcus Mariota game-time decision vs Dolphins

FILE – In this Oct. 1, 2017, file photo, Tennessee Titans quarterback Marcus Mariota (8) walks off the field after suffering a hamstring injury during the third quarter of an NFL football game against the Houston Texans at NRG Stadium in Houston. Titans coach Mike Mularkey hoped to know more about how quickly his quarterback Marcus Mariota might heal up from a strained hamstring by Wednesday, Oct. 4, 2017. Tennessee has added Brandon Weeden as a third quarterback just in case Mariota isn’t available Sunday against Miami. (Brett Coomer/Houston Chronicle via AP, File)
