With center Kwame Brown likely out for the season, the Warriors are back on the market for a big man. Only this time, the options are even skimpier.

Thursday, Golden State announced Brown will have to undergo surgery to repair a torn pectoralis major (the large chest muscle that attaches to his right shoulder). It is expected to keep him out at least three months, according to the Warriors.

"It's a tough loss," coach Mark Jackson said. "This guy has done everything we have asked him to do. He's brought toughness, a presence to this basketball team -- it's a tough loss for us. He was a jewel for us, a great find, and hopefully he'll back soon with us soon and continue his great career."

Brown -- who signed a one-year, $7 million deal just over a month ago -- will have surgery in the next few days. General manager Larry Riley said the team won't know for sure how long he's out until after the surgery.

Brown, who was averaging 6.3 points and 6.3 rebounds in 20.8 minutes, suffered the injury in the fourth quarter in Tuesday's win over Miami, applying a hard foul on Heat forward Udonis Haslem. Based on preliminary estimates, he wouldn't return until about mid-April barring no setbacks. The regular season ends for the Warriors on April 26. He could get back sooner, but that would be necessary only if Golden State were in the playoff hunt.

With Brown out, Andris Biedrins is the only true center on the roster. Warriors management is already working the phones trying to land a big man.

According to multiple sources, the Warriors had Joel Przybilla on their list. But Przybilla, an 11-year veteran defensive specialist who last played for Portland, has been ruled out because he's seeking to play for a title contender.

Golden State previously had an agreement with free agent center Kyrylo Fesenko, formerly of Utah. But after he worked out with the team, the Warriors decided to pass. One team source said Golden State would not take another look at Fesenko.

Whoever the Warriors add will likely mean the departure of point guard Ish Smith. Golden State is currently at the maximum of 15 players, which means the team would need to waive someone to create a roster spot.
