Quarterback situations are iffy for the Tennessee Titans and Jacksonville Jaguars as the AFC South doormats prepare to meet in Florida on Thursday in a game that could help determine the No. 1 draft choice. The Titans, losers of eight straight, will stick with third-stringer Charlie Whitehurst after he finished the team's 16-11 loss to the New York Jets on Sunday. The Jaguars are also preparing for a possible change at QB as rookie starter Blake Bortles is questionable with a sprained foot.
