Odom, who fell awkwardly while attempting to drive during
the third quarter of Sunday's surprise 99-87 loss to the Rockets
in Houston, had a CT scan and MRI on Monday morning.
The scan showed he had a lower back contusion, and a final
decision on his ability to play will be made before Tuesday morning's
shootaround, the Lakers said on their Web site.
Los Angeles is tied 2-2 with Houston in their Western
Conference semifinal series after squandering a golden
opportunity to go 3-1 up against a Rockets team missing the
pivotal Yao Ming because of injury.
Chinese center Yao broke his left foot in Friday's loss to
the Lakers, but Houston shrugged off his absence by outplaying
the top-seeded Lakers on Sunday.
"We just happened to play probably our worst game of the
year," Odom told reporters. "It hurts. We got beat.
"Now we go back home. Hopefully I will be able to help the
team on Tuesday."
