IRVING, Texas » Welcome back, Kosier.

And Colombo, too.

For the first time in four weeks, the Dallas Cowboys had their starting offensive line intact for practice. Left guard Kyle Kosier (knee) and right tackle Marc Colombo (knee) practiced yesterday and are expected to play Sunday against the Chicago Bears.

"They’re two experienced players who have played a lot for us, and that’s valuable," Cowboys coach Wade Phillips said.

Backup tackle Alex Barron had three holding penalties in his first game with the Cowboys, including one on the final play that negated a touchdown in a 13-7 loss to the Washington Redskins.

"It was a tough week," said Barron, acquired in an offseason trade with the Rams for Bobby Carpenter. "You never want to have a game or plays like that, being that the game could have been won. It was one of those things you’ve got to deal with and look at the tape and talk about a couple of things to work on and work on those things and get better."

Barron has more holding penalties — 10 total and eight accepted — over the past two seasons than any other player in the league. In his six seasons, he has 66 penalties for 427 yards, including 16 holds. He has allowed 33 career sacks for 235 yards.

Cowboys offensive line coach Hudson Houck said he can fix Barron’s holding problem.

"It’s all technique," Houck said. "It’s not athletic ability; it’s not ‘want to’; it’s not preparation. Some of the issues are how he sets, and what he does. We’ll address it; we’ve got the answer. We’ve just got to get it now where it’s a habit."

Colts S Sanders could be done

Indianapolis Colts safety Bob Sanders, the 2007 NFL defensive player of the year, had surgery yesterday to repair a torn biceps muscle in his right arm, an injury that could end his season again. Team officials are not yet saying how much time Sanders could miss.

Just 10 months ago, Sanders went on season-ending injured reserve with a torn biceps in the left arm. Since winning the league’s top defensive honor and signing a $37.5 million contract after the 2007 season, Sanders has played in just nine games. He’s missed more games (49) than he’s played in (48) during his seven-year career.

Hill will start for Lions

Matthew Stafford got a second opinion on his injured right shoulder, and the diagnosis was the same as the first — no surgery necessary, and no chance of starting this weekend.

Detroit Lions coach Jim Schwartz said yesterday that backup quarterback Shaun Hill will start Sunday’s home opener against the Philadelphia Eagles, but once again declined to put a timetable on Stafford’s return.

Seahawk LB back

After a rough few months filled with off-field drama, Seattle linebacker Leroy Hill returned from his one-game suspension and rejoined the Seahawks yesterday.

He’ll play on Sunday in Denver. Hill missed the season opener as punishment from the NFL for his arrest on a marijuana-possession charge in Georgia. He began 12 months of probation for that in April.

Season over in a snap

Long snapper David Binn, who accurately delivered the ball to San Diego Chargers punters and kickers since 1994, was placed on injured reserve yesterday because of a hamstring injury, meaning his season is over.

The popular 17-year veteran was the only player left from the Chargers’ 1994 Super Bowl team, and the last player left from Bobby Beathard’s tenure as general manager.
