Warriors center Andris Biedrins will miss at least two weeks of action after aggravating a back injury on Sunday.

Biedrins originally hurt his back against the Timberwolves last Wednesday. He missed the team's game against the Clippers on Friday and then tweaked his back on Sunday in a game versus the Kings.

He is suffering from Osteitis Pubis, which is characterized by inflammation of the muscles attached to both the groin and abdominal.

Golden State will re-evaluate Biedrins on Nov. 23, which means he'll miss the team's five-game road trip.
