An unexpected development happened surrounding Lamar Odom, something that pales in surprise perhaps only to his own survival.

It has been determined in recent days that the former Lakers and Clippers forward will not need a kidney transplant, according to multiple sources familiar with his recovery.

Still, Odom awaits other challenges.

Odom plans to seek counseling for drug addiction, according to multiple sources familiar with his recovery.

Witnesses had reported in 911 calls that Odom overdosed on cocaine and 10 doses of a sexual enhancer through three days. The Nye County Sheriff’s office has since analyzed the results of Odom’s blood tests. But they have handed over the findings to the district attorney’s office. It was not immediately clear when the results would be released.

Still, optimism continues to bloom about Odom’s recovery.

Odom was earlier expected to need a kidney transplant because of the potential long-term damage he suffered after losing consciousness two week ago at a Nevada brothel.

Odom also has gone through intensive dialysis treatment that lately has lasted about six to eight hours a day at Cedars-Sinai Medical Center in Los Angeles.

Odom had previously stayed at Sunrise Hospital and Medical Center in Las Vegas where his dialysis treatment lasted 11 to 12 hours per day, sources said.

But Odom has undergone various tests in recent days to treat a kidney infection that has since healed, according to multiple sources familiar with his recovery. That coincides with ongoing improvements he made with his breathing, vision and talking, sources said.

Odom has become increasingly tired throughout his early stages of physical therapy, sources said. Although Odom had started walking last week, he has taken limited steps, sources said.

Hospital officials have restricted visits to the former Lakers and Clippers forward in hopes of aiding his recovery, sources said.

Alvina Alston, who is the publicist for Odom’s aunt JaNean Mercer, declined to comment on Odom’s latest developments. But Alston expressed continued optimism about Odom’s progress.

“He was born with the blood of a champion,” Alston wrote in a text message to the Los Angeles News Group. “He has overcome so much adversity and this is no different. Lamar Odom = Leader Overcomer!”
