The Texans wrapped up their preparations for the Dolphins Friday with an indoor practice -- a practice in which center Steve McKinney participated.
"Steve practiced today so I would say that we'll certainly work him out before game time," Capers said. "But I think Steve is anticipating playing and we're anticipating having Steve play."
McKinney started all 16 games at center last season and has never missed in a season opener in his five years in the league, a streak he doesn't want to break -- especially considering his younger brother, Seth, plays for the Dolphins.
"It's always nice to see your brother, especially when he's on the opposing sideline," McKinney said.
Meanwhile, defensive end Gary Walker's status for Sunday remains tenuous. Walker is listed as questionable with his shoulder sprain and the Texans will also wait until pre-game warm-ups to make a decision on the two-time Pro Bowler.
"Gary Walker's situation is the same," Capers said. "With a guy like Gary, he's played enough in this defense, as opposed to somebody with less experience who hasn't had the chance to practice all week. But with a Pro Bowl player, you're always going to take it up to game time and see how he feels."
The Texans pumped up the volume inside the bubble with some crowd noise in anticipation of a rowdy gathering at Pro Player Stadium. Capers was encouraged by his team's focus.
"I thought we had a good, spirited practice," he said. "Our guys certainly understand the challenge we're up against going to Miami."
