CLEVELAND (WRCB) - A Bradley County girl, in need of a bone marrow transplant, will have surgery by the end of the month.

We first introduced you to Haley Brooks in March, when her best friend organized a blood marrow drive in her honor.

Haley found a perfect match.

She went to Vanderbilt Tuesday for some tests..

She'll go through chemo, and have some time to rest before her surgery later this month.

Haley has a rare blood disease, and must have a blood transfusion every other week.

We'll keep you updated on Haley's condition.
