Leah Still, daughter of Cincinnati Bengals defensive tackle Devon Still, is facing a recent complication from stem cell treatment.

On Friday night, Still posted, "I need some prayers sent up for Leah tonight! We hit a pretty serious complication from the stem cell transplant called VOD”.

Devon Still has kept everyone up to date through his Instagram account on how his daughter’s battle with neuroblastoma has been going. He keeps on posting images and messages that are often inspiring.

He recently updated everyone on her health and let everyone know that Leah had a pretty serious complication from the transplant called VOD.

VOD is a condition that causes obstruction of veins in the liver. It is a result of high doses of chemotherapy. Fortunately, it sounds like doctors were able to catch it early on in the process to stop it from getting aggressive.

According to the American Cancer Society, VOD, or Hepatic veno-occlusive disease happens only in people with allogeneic transplants, and primarily in those who received two types of drugs, busulfan or melphalan, as part of their post-cancer recovery.

It can be more common in older people who had liver problems before the transplant. The disease's reported incidence is between five and more than 60% in children who have undergone stem cell transplantation.

Leah was diagnosed with neuroblastoma in June 2014. In late March, her father announced that she was officially in remission. However, she had to go through stem cell treatments in order to get her immune system back to normal. The treatment was expected to last four to six weeks.

Bengals were joined by other NFL teams to raise funds and awareness for pediatric cancers. Last November, based on a sale of Still's black No. 75 jersey, the Bengals donated more than $1.2 million to pediatric cancer research initiatives.
