Brook Lopez out Friday. No date set for return

Brook Lopez was doubtful for the Nets season opener against the Boston Celtics on Wednesday, and his status for the Nets second game is the same. He's out, Lionel Hollins announced. The Nets All Star big man was out of practice Friday after practicing non-contact two times earlier in the week.

No timetable on when Brook Lopez will return to practice. Will not play tomorrow.

Lionel Hollins on Brook Lopez's health: "I was optimistic everyday. When he doesn’t come out and practice, I’m not optimistic any more."

Deron Williams said Lopez was at his Halloween party as a Power Ranger on Thursday.

As he did in Boston, Mason Plumlee will start in Lopez's place.

Billy King told the media earlier in the week that if Lopez couldn't play against the Celtics, he would be available on Saturday or Monday for the team's home opener against the injury-riddled Oklahoma City Thunder.

The Pistons will have Greg Monroe back for the game. He has been serving a two-game suspension for driving while visibly impaired" in the state of Michigan" over the offseason. Nets could use Lopez against the big Detroit frontcourt as they missed the big man's presence in the paint. They allowed 62 points in the paint Wednesday night to Boston.

Lopez was ruled out 10-14 days when the initial report was released from the Nets, Thursday was day 14. Saturday would be 16 days.
