After fully practicing Wednesday, offensive tackle Jared Gaither was downgraded and did not participate this afternoon. Gaither, who has missed the Ravens' last two games after suffering a scary neck injury in the second quarter of a 27-21 loss to the New England Patriots on Oct. 4, wore a red, non-contact jersey during the portion of practice open to the media. Gaither has said he intends to play Sunday against the Denver Broncos.

Free safety Ed Reed, who did not practice Wednesday due to illness, returned to full participation. Linebacker Tavares Gooden, who suffered a slight concussion during practice Monday and sat out Wednesday's session, was limited.

Quarterback Joe Flacco (sprained right ankle), linebacker Jarret Johnson (left shoulder), kicker Steve Hauschka (right ankle) and wide receiver David Tyree (hamstring) practiced fully.

For the Broncos, a pair of starters in safety Brian Dawkins (hamstring) and nose tackle Ronald Fields (hamstring) were limited.
