Our worst fears about the fourth preseason game could be realized. The KC Star's Adam Teicher reports Kansas City Chiefs linebacker Derrick Johnson has an ankle injury that "could be significant."

That's not good. That's really not good. That he "could" have a major injury suggests there's a reason to believe he does have a major injury.

DJ hasn't missed a game for the Chiefs in two years. He's the best inside linebacker on the Chiefs and one of the better ones in the league. Losing him for any amount of time would be a huge blow to the Chiefs defense, especially in Week 1 when Tamba Hali is already out.

I'm nervous about this one, folks. Let's hope good news is coming soon.
