Raiders deny interest in QB

The Oakland Raiders have plenty of roster moves they need to make before the start of the season.

Apparently trading for Matt Leinart isn't one of them. The Raiders denied a report from ESPN on Wednesday that said the team has had discussions about trading with Arizona for Leinart.

"The Raiders have never discussed trading for Leinart," the team said in a statement. "The Raiders are very happy about their quarterback situation."

Oakland acquired Jason Campbell in an offseason trade with Washington and is pleased with what he's brought as the starter. Campbell led Oakland to touchdowns on the opening drives of the last two exhibition games. He sustained a stinger and an injured right wrist last week against San Francisco but is expected to be ready for the season-opener Sept. 12 in Tennessee.

Bruce Gradkowski and Kyle Boller are slated to be the backups as quarterback appears to be one position that is set heading into the final exhibition game against Seattle tonight.

Redskins sign Beck to be No. 3 QB: The Washington Redskins have signed quarterback John Beck to a two-year contract extension.

The move Wednesday puts Beck under contract through the 2012 season and appears to solidify his spot on the roster as the third-string quarterback. He had been competing with Richard Bartel for the No. 3 spot behind Donovan McNabb and Rex Grossman.

Cardinals extend Dockett's contract: The Arizona Cardinals have signed Pro Bowl defensive tackle Darnell Dockett to a four-year contract extension.

The deal keeps Dockett under contract through the 2015 season. A third-round draft pick out of Florida State in 2004, Dockett has developed into one of the best at his position entering his seventh NFL season as the high-spirited leader of the Arizona defense.

Placement of umpires under scrutiny: The NFL will move umpires back to their old spots during the final five minutes of Thursday's preseason games.

Previously they were in the old spot for only the final two minutes of each half.

NFL spokesman Corry Rush confirmed the adjustment Wednesday.

League officials decided to move umpires from the old spot, in the middle of the defense, to behind the deepest running back for safety reasons. But Peyton Manning complained about the switch after being called twice for illegal snaps when the umpire couldn't get into position quickly enough last week at Green Bay.

The NFL will again re-evaluate the new policy after this week's preseason finales. The change could become permanent when the regular season starts.

Roethlisberger wants to play final exhibition: The Pittsburgh Steelers will get one last brief glimpse of Ben Roethlisberger playing quarterback before he begins his NFL-mandated suspension.

They can only wonder what position they'll be in when Roethlisberger returns to the field in October.

While the starters usually play only a couple of series in the final exhibition game, Roethlisberger is lobbying to take snaps in the no-huddle offense Thursday night against Carolina. New center Maurkice Pouncey and right tackle Flozell Adams haven't worked with Roethlisberger out of that formation except during practice.

Roethlisberger will take the field only a few hours before he travels to New York to meet Friday with NFL commissioner Roger Goodell.
