PORTLAND, Ore. — The Charlotte Bobcats are down a captain and won't be getting back their sixth man for another 10 days.

As suspected, small forward Gerald Wallace suffered a collapsed lung and a broken rib in Tuesday's fourth-quarter collision with Los Angeles Lakers center Andrew Bynum. Wallace is still in a Los Angeles hospital and coach Larry Brown said, "I don't expect him back anytime soon."

Meanwhile, rookie point guard D.J. Augustin (abdominal strain) had a setback in his rehab. Augustin started feeling pain when he would stop and start in drills, and a Los Angeles-based specialist advised him to wait another 10 days before playing.

Augustin has missed eight games, and was aiming for a return Friday against the Denver Nuggets.

Suddenly shorthanded, the Bobcats plan to sign 6-7 small forward Cartier Martin to a 10-day contract today. A former Kansas State player, Martin is averaging 20.6 points and 5.4 rebounds for the Iowa Energy of the NBA's developmental league.

But the main concern is Wallace, who could miss several weeks. The injury occurred with about two minutes left in regulation when Wallace beat Kobe Bryant off the dribble and drove the lane. Bynum cut Wallace off, then elbowed Wallace in the rib cage.

Bynum was called for a flagrant foul and an NBA spokesman said the league is reviewing the play to determine whether further discipline should be administered. However, Brown doesn't advocate a suspension or upgrading the foul to the more-serious Flagrant-2 level.

"That kid waited at our bus, trying to get to Gerald, and he apologized to me," Brown said. "If he had a history of that (rough play), I might feel different, but I just think it was a hard foul."

Brown planned to start Adam Morrison in Wallace's place versus the Portland Trail Blazers, but he's looking at all sorts of alternatives to fill the gap left by Wallace's and Augustin's absence.

Brown plans to lean heavily on Boris Diaw's versatility. The starter at power forward, Diaw will play a lot more small forward now, with Juwan Howard playing more off the bench at power forward.

Diaw might also play some at point guard, since rookie Sean Singletary hasn't fared particularly well as the backup. There's also some chance the Bobcats could sign a veteran point guard, although that would require opening a roster spot.
