Yeah, I'm guessing it means they know it's a high ankle sprain and he's going on the IR.
Agree with Aggie that it might have a silver lining, though I think if we were going to play that game with an injury, it would have been better if JJ had gotten a couple more weeks to learn from yesterday's loss, THEN let Wentz take all the lumps facing an absolute brutal schedule of the Eagles, Chargers, Lions and Ravens.
Wentz's worst habit is holding on to the ball too long too. Lucky for him and the Vikings, the Bengals are a great fix for that problem.
