NEW YORK — The real referees will work the real games.

The NBA and its referees union agreed on a two-year contract last night, ending a lockout of more than a month and saving the league from using replacements when the regular season starts.

The officials ratified the deal that was reached earlier this week in a vote last night. No details of the vote were provided, nor were terms of the agreement.

"We are pleased to reach this agreement," NBA commissioner David Stern said in a statement. "The negotiations extended further than either side had hoped, but when our regular season tips off on Tuesday we'll have the best referees in the world officiating our games."

The referees union did not comment.

The referees will begin a three-day training camp today and be ready when the regular season starts Tuesday.

The contract between the league and the National Basketball Referees Association expired Sept. 1, and the league announced it was locking out the officials on Sept. 18, saying they had rejected its final contract offer.

The NBA decided to go with replacements late last month after the referees rejected a deal the league said its negotiators had already agreed to.

But progress was made in a meeting this week that included Stern, who had previously pulled out of the negotiations after referees lead negotiator Lamell McMorris criticized the commissioner's behavior.

BLAZERS

ALDRIDGE SIGNS DEAL

With forward LaMarcus Aldridge's contract extension, the Portland Trail Blazers solidified the core of their team for the next five years.

During the summer, the Blazers signed guard Brandon Roy to a five-year extension. On Thursday, they did the same with Aldridge.

With the Oct. 31 deadline looming, the Blazers needed to strike a deal with Aldridge or he would have become a restricted free agent next summer.

Aldridge signed a deal that with incentives will pay him up to $70 million.

BULLS

ROSE STILL HURTING

The Chicago Bulls held Derrick Rose out of their preseason finale against the Washington Wizards because of a nagging ankle injury.

The NBA's reigning Rookie of the Year, Rose has an inflamed tendon behind his right ankle. He practiced Thursday and was hoping to play last night for the first time since the preseason opener, but the Bulls took a cautious approach. He expects to be ready for the season opener against San Antonio on Thursday.

The Bulls also held out guards Kirk Hinrich (left elbow) and Jannero Pargo (lower back).

GRIZZLIES

IVERSON WON'T PUSH

For the first time in his career, Allen Iverson vows to take the advice of others instead of listening to his body.

That means the 10-time All-Star could miss Memphis' season opener Wednesday night against his former team, Detroit, as he recovers from a partly torn left hamstring.

Iverson indicated there's a good chance the Grizzlies' medical staff won't clear him for the opener because of fears he's not completely healed.

"They're saying it's a possibility, but it's also a long shot," said Iverson. "You know that's one of the ones I definitely want to play."

WIZARDS

JAMISON OUT LONGER

Antawn Jamison's ailing shoulder will keep him off the court well into the regular season.

The Washington Wizards announced an estimated recovery time for Jamison's injury yesterday, saying he's likely to miss the first eight to 13 games.

The two-time All-Star forward partially dislocated his shoulder trying to block a shot in an exhibition game against Cleveland on Oct. 14.

OVER AND BACK

Jazz: Utah said forward Kyle Korver will have surgery on his left knee Tuesday in New York and will miss the beginning of the regular season.

Korver has been bothered by inflammation in his left knee. He has appeared in just one preseason game.

Rockets: Houston waived 14-year veteran guard Brent Barry, a move that trims its roster to the required 15 players.

Barry, 37, signed as a free agent with the Rockets before last season and averaged 3.7 points and 1.4 assists in 56 games.

Thunder: Oklahoma City exercised fourth-year contract options on Kevin Durant and Jeff Green and third-year options on guard Russell Westbrook and forward D.J. White.

All four are now under contract with the Thunder through the 2010-11 season.
