"Linebackers coach Reggie Herring has praised former defensive end Mario Williams for how quickly he is learning his role at linebacker.

"Mario is getting more and more comfortable with the system," Herring said. "His change of direction and movement is just as good as any of the other linebackers."

Early on in camp, Williams battled the habit of getting into a three-point stance. But lately he has resisted the urge to put his hand on the ground.

New corner Johnathan Joseph saw plenty of Andre Johnson on Sunday, as the Pro Bowl receiver returned from sitting out five days with a compound dislocation of his left index finger.

"I think we're both making each other better," Johnson said of competing against the former Bengal. "We're all working to make this team better. He's a great player. That's why we brought him here."

Responded Joseph: "It was a great competition. Andre is the best receiver in this game, and it's just a great pleasure to have him out here. As a defensive unit, it will only make us better."

Johnson had tested his injured hand Saturday, and although he felt pain, he thought he was ready.

"I had it protected and I had it taped up pretty good," he said. "After I caught some balls yesterday and felt comfortable doing that, that's what made me come out and practice today."

Quarterback Matt Schaub admitted he thought Johnson had lost some conditioning because of the layoff."
