There's still no clear answer on exactly what is wrong with Brandon Flowers, who has officially been ruled out of Saturday's game against the St. Louis Rams. On July 31 he left the Kansas City Chiefs training camp night practice with what was soon dubbed a bruised heel. Since then, it seems his return is only a day or two away. Check out what I wrote about his injury just a couple days after it happened. No concern over Flowers in that post.

Except now this has now been going on for two and a half weeks.

"He's still working to try to get better," Romeo Crennel said on Thursday. "I saw him this morning, and he's doing all that he can. We're sending him to the doctors and we're trying different things to try and get it better. He's getting better slowly, not fast enough, but all we can do is kind of hang on and see what happens."

The part about seeing multiple doctors was mentioned yesterday and that worries me a little bit. Tells me there's still an unknown element to Flowers' injury. That could be good or bad.

"I don't know [if it's worse than we initially thought], not necessarily," Crennel said. "It's just one of those things that they haven't been able to pinpoint exactly why he's not getting better as fast as we want him to get better."

The Chiefs are obviously frustrated with the situation. I would imagine Flowers, who has missed four career games, is frustrated as well. And that's the thing -- Flowers doesn't miss a lot of time. He started all 16 games last year. It's not like the Chiefs have experience playing without their top cornerback.
