Backup point guard Steve Blake has encountered complications following surgery for a torn abdominal muscle and there is no timetable for his return, the Lakers said Tuesday.

Blake was originally diagnosed with an abdominal strain Nov. 12, but when the injury did not respond to usual treatment or an injection of platelet rich plasma (PRP), the guard opted for laparoscopic surgery that was performed Dec. 3 by Dr. Craig Smith.

For a PRP treatment, doctors take a small amount of a patient's blood, separate the platelet-rich plasma in a centrifuge and inject it into the affected area. It can speed up the healing process by 50 percent and eliminate the need for more aggressive treatments or surgery.

While his abdominal muscle has healed, Blake has been experiencing a different pain, this one in a muscle near his groin area that continues to limit his movement. Team doctor Steve Lombardo said this injury is more commonly seen among soccer or hockey players.

"This is not a typical basketball injury although Shaq (O'Neal) had a minor variant of that and we got him better with treatment," Lombardo said.

The groin pain began before Blake had abdominal surgery and neither he nor the medical staff initially believed his discomfort to be serious.

"He didn't think it was very significant, minimal in his opinion," Lombardo. "And he, along with the training staff and the four doctors that examined him, thought it was something that would just take care of itself. It usually does."

The new pain continued to increase during his rehabilitation following surgery and Friday he had a PRP injection in his groin muscle. Lombardo said it's too soon to tell whether the injection would speed up the healing process.

"We're in a holding pattern now," Lombardo said. "Hypothetically, if he doesn't get better ... (doctors) will access whether anything further needs to be done to this other muscle that was a lesser part of the problem when it began."
