Maurice Jones-Drew has been a Titans killer in his career, so it is not the best news in the world that he is expected to play. The Titans did do a good job against him in the first game outside of the touchdown run. He finished that match-up with just 41 yards on 21 carries.
The Titans have been gashed by the run in recent weeks. Hopefully that trend doesn't continue today, but the job just got a little bit tougher with this news.
