CHARLOTTE, N.C. — Charlotte Bobcats forward Gerald Wallace suffered a partially collapsed left lung and a fractured rib late in the team's double-overtime victory over the Los Angeles Lakers, team officials said Wednesday.

Wallace scored 15 points before a flagrant foul by Andrew Bynum knocked him to the floor with 2:08 left in the fourth quarter of Tuesday night's game, which the Bobcats won 117-110.

A statement from the Bobcats said Wallace was taken off the floor and underwent X-rays at the Staples Center. Preliminary results were inconclusive, prompting Lakers team physicians to arrange a second examination.

The statement said Wallace had 30 to 40 percent of his left lung collapse as well as a non-displaced fracture of the fifth rib. The team said Wallace underwent a CT-scan at Centinela Hospital in Los Angeles, and had a chest tube inserted into the lung to help restore full function.

Wallace was to remain in the hospital over the next 48 hours for observation and did not accompany the team to Portland for Wednesday night's game against the Trail Blazers.

Team spokesman B.J. Evans said there was no immediate indication on when Wallace would rejoin the team, or even when he would return to Charlotte. Evans also said there had been no decision Wednesday afternoon as to who would replace Wallace in the starting lineup against Portland.

In 41 games this season, the 6-foot-7 Wallace was averaging 16.4 points and 7.4 rebounds per game for the Bobcats, who beat the Lakers for the fifth time in their last six games against each other. Charlotte's victory was just its sixth on the road against 13 losses.

Kobe Bryant scored a game-high 38 points before fouling out for the first time this season in the final minute of the first overtime.

The Lakers are 4-5 overall against the Bobcats, who joined the NBA as an expansion team in 2004.
