CHARLOTTE -- The Warriors made the signing of center Earl Barron official Saturday.

Barron, brought in to fill injured center Kwame Brown's spot in the rotation, took part in the team's shootaround and will be in uniform tonight. Barron -- who stands 7-feet and weighs 250 pounds -- is in his fifth year out of Memphis.

"We're going to ask him to battle defensively and continue to hold the same principles that we have on that end," Warriors coach Mark Jackson said. "It's very important. We need that depth to continue to have our identity, to give us a chance to be a force in the interior defensively."

Barron was with the Portland Trail Blazers during training camp, getting waived just before the season. He's played for Miami, New York, Phoenix, Milwaukee and Portland. His best season as a pro was in 2007-08, when he averaged 7.1 points and 4.3 rebounds in 19.3 minutes with the Heat. He made a career-high 46 appearances that season, including 15 starts.

The Warriors signed Barron because Brown is out for at least three months after tearing a muscle in his chest, which will require surgery. But Jackson said don't expect Barron to fill the shoes of Brown.

"We're not going to find Kwame Brown right now, or a Kwame Brown type player," Jackson said. "(Barron's) a different guy. He's a weapon offensively. He can knock down the jumper. When you think about how Dwight Howard was allowed to play us, basically playing center field defensively and not having to pay the price, a guy like Earl Barron gives us a chance to have a range-shooting big."
