Houston, TX -- (Sports Network) - Houston Texans linebacker Brian Cushing and wide receiver Andre Johnson returned to full practice on Friday and are both expected to be ready for the team's road game at Buffalo on Sunday.

Cushing has been dealing with a bothersome foot injury that had kept him out of drills the previous two days. The rookie out of USC has 56 tackles and one interception over seven games in 2009.

Johnson, who was suffering from a lung contusion after last weekend's 24-21 win over San Francisco, looks like a go for the Bills matchup after returning to the practice field in full participation. He was limited on Thursday and sat out Wednesday's session.

In addition, defensive end Tim Bulman (ribs) was limited in drills on Friday and is listed as questionable, while safety Eugene Wilson (groin) and tight end James Casey (knee) remain in question for the weekend despite taking full reps on Friday.
