Adam Schefter just tweeted that Jake Locker is not expected to play this Sunday when the Titans travel to Minnesota to take on the Vikings this Sunday. I have no idea who Schefter got his information from or if it is any good, but my guess is that not expected to play is the best anyone can guess at this point. Locker is going to have quite a bit to say about whether or not he plays.
We have drawn the comparison of Locker to Steve McNair here many times. I can't help but wonder how many times Adam Schefter would have tweeted on a Monday night that McNair was not expected to play the following Sunday had Twitter or Schefter been around back then. It is just too early to tell if he will be ready or not.
As I said earlier, we will know a lot more once we see what Locker is able to do in practice this week.
