Peyton Manning tries to avoid a third surgery on his neck by traveling to Europe for stem cell treatment, according to a report on Fox's NFL pregame show

snip:
NFL players hoping to extend their playing career apparently don't think stem-cell treatment is a bad idea. Last week came a report that injured Indianapolis Colts quarterback Peyton Manning had stem cell therapy in Europe before having a third neck surgery this month. Now comes a new report that free agent wide receiver Terrell Owens is in South Korea for a three-day stem-cell therapy treatment.
The Korea Times reported Tuesday that Owens, hoping to continue his NFL career, is currently in South Korea for stem-cell therapy on his surgically repaired ACL. Owens has so far been unable to get signed as a free agent, and he's apparently hoping the treatment will speed recovery from the off-season ACL surgery.
