As Ravens cornerback Chykie Brown returned to practice on a limited basis with a minor right knee injury, Houston Texans wide receiver Andre Johnson was also back to work.
Johnson practiced for the first time this week since sustaining a concussion against the Tennessee Titans when he got hit by former Ravens safety Bernard Pollard, who was fined $42,000 by the NFL.
Ravens wide receiver Deonte Thompson didn't practice due to a left foot sprain that's still bothering him after practicing Wednesday on a limited basis.

Defensive tackle Brandon Williams (right big toe) is limited.
For the Texans, offensive tackle Duane Brown (toe) didn't practice again and is regarded as a question mark for Sunday.
Tight end Garrett Graham was downgraded to not practicing due to a hip and groin injury.
Former Ravens free safety Ed Reed (hip surgery) was limited again as well as offensive guard Wade Smith (knee).
Running back Arian Foster practiced fully with calf, chest and thumb injuries and running back Ben Tate (shoulder) was added to the injury report with full participation.
