For a team that's played only 14 games, the Lakers don't have much in reserve.

Their bench entered Saturday night's game against the Clippers averaging an NBA-worst 21.3 points per game. Things bottomed out Friday against Cleveland when the Lakers reserves combined for only four points.

And it could get worse.

Steve Blake, the Lakers' primary fourth-quarter point guard and leading scorer off the bench, will be sidelined up to a month after fracturing the cartilage that connects the rib to the sternum earlier this week.

That leaves the Lakers to rely on the erratic Metta World Peace and other players who haven't provided much of a boost to the starters.

Coach Mike Brown had projected World Peace as being a low-post force capable of averaging double figures in scoring upon his move to the bench this season; the small forward was averaging a career-low 5.9 points per game before Saturday.

The Lakers also have received only pockets of production from Jason Kapono, Luke Walton and Devin Ebanks, and injuries and illness have sidelined Josh McRoberts and Troy Murphy for stretches.

McRoberts said the bench's lack of production could be attributed in part to having a starting unit that includes the NBA's leading scorer in Kobe Bryant as well as the reserves trying to learn their roles under a new coach early in the season.
