"Four players — receiver Andre Johnson (ankle), defensive end Mario Williams (hip), tight end Owen Daniels (hamstring) and linebacker Xavier Adibi (hamstring) — didn't practice Wednesday.

Johnson may not practice this week, but he's expected to play against San Diego. Williams and Daniels are also expected to be back by then.

"We'll stay with our plan," coach Gary Kubiak said about Johnson aggravating his high ankle sprain.

Kubiak said the others are day-to-day.

Kris Brown, the last original Texan, will kick for the Chargers on Sunday. The Chargers signed Brown until Nate Kaeding recovers.

Coach Gary Kubiak elected to keep Neil Rackers over Brown after they competed in training camp and preseason."
