Texans owner Bob McNair ordered the team's staff to go through the locker room to make sure no players are using banned substances. Houston had staff members remove any products from lockers that are not approved by the NFL. Two of Houston's players -- left tackle Duane Brown and linebacker Brian Cushing -- served four-game suspensions for different violations of the league's policy on banned substances. McNair said Friday he wanted to take a step to prevent future occurrences.

Randy Moss was relatively quiet, but led Minnesota with five catches for 55 yards.

Texans linebacker Demeco Ryans will miss the rest of the season after tearing his left Achilles tendon against the Chiefs on Sunday. Ryans jumped and fell to the turf on a touchdown by Kansas City. He has had more than 110 tackles in each of his first four NFL seasons.

Texans linebacker Brian Cushing says that his recent four-game suspension will motivate him on the field this season. Cushing has been criticized for the suspension, which came from violating the NFL's steroid policy. "That's what gets me through the fourth quarter," Cushing says. "The suspension is going to motivate me until the day I die." The young defender's family continues to maintain his innocence.

Texans defensive end Mario Williams has been slowed in practice by a groin injury this week. Williams is listed as questionable for Houston's game against the Giants this weekend. He has five sacks and a forced fumble this season.

Texans wide receiver Andre Johnson was reportedly wearing a brace on his injured right ankle during practice on Thursday. Houston will face the Giants on Sunday. "The brace stabilizes my ankle," Johnson told the Houston Chronicle. "It's still sore. I want to play. I hope to play. I'll get back out here [Friday] and do some more and see how it feels." Johnson sat out last Sunday's game against the Raiders after hurting the ankle in Week 2 and aggravating the injury in Week 3. "Andre took what we expected for him to take today," Texans coach Gary Kubiak said. "He was limited for practice, but he did practice, and we'll see how he'll come out of it. It was very encouraging as we work toward the [New York Giants game]. "There's going to be a risk whenever he comes back, regardless. We would never put a guy out there if we think he can't protect himself and play at the level that we think that he could play at. This week will be no different from last week from that standpoint, but he's way ahead of where he was last week at this point."

The Texans will sign free-agent defensive end Mark Anderson, according to a league source. Chicago released Anderson earlier this week in part to make room for signee Charles Grant.

Andre Johnson received platelet-rich plasma therapy (commonly known as PRP) to treat his high-ankle sprain, a source told FanHouse. Johnson is listed as day-to-day for Sunday's game against Oakland. A source told FanHouse that the Texans have used platelet-rich plasma therapy to aid a number of players in healing injuries.
