Linebacker Lawrence Timmons did not practice yesterday for the fourth consecutive day.

Although he is officially listed as doubtful for the game tomorrow night in Denver, players who cannot practice almost never play in games.

Safety Ryan Clark participated fully in practice but is listed as questionable and not expected to play because of health concerns related to sickle-cell anemia.

Defensive end Travis Kirschke (torn calf muscle) also is listed as doubtful.
