It appears that Warriors center Patrick O'Bryant's rookie NBA season has reached an early end.

Warriors Coach Don Nelson indicated Wednesday that O'Bryant, the ninth overall pick last summer, probably would not be recalled from his assignment with the Bakersfield Jam before the NBA Development League season concludes April 14. Golden State would have three regular-season games remaining at that point.

O'Bryant, the only NBA lottery selection to receive the D-League treatment, is averaging 6.1 points, 6.7 rebounds and 2.1 blocks in seven games with the Jam but has fouled out twice and shot just 40 percent.

``I told him if he goes down to the D-League and isn't a dominant player, there should be red flags all over the place, and he should be the first to notice,'' Nelson said.

``He's not only not dominating, he's not playing very well. He's a long-term project. I really liked him the first week of training camp, but I assumed there would be great progress. He hasn't gotten better one bit.

``I'd like to go to dinner with him, but I wouldn't like to put him in the game I'm coaching.''
