Titans coach Mike Mularkey has changed his tune a bit in regards to running back DeMarco Murray, or at least wants the Jaguars to think he has. Via Jim Wyatt of the team’s official website, Mularkey said Tuesday that Murray was a “tough guy” and declared him “day to day,” with a knee injury, refusing to rule him out for this week’s regular season finale against Jacksonville. Murray suffered a knee injury late in the loss to the Rams, and he’s had an MRI.
