BOISE -- On Monday, March 21, 20-year veteran teacher and Bishop Kelly's head girls basketball coach and varsity baseball assistant coach Derek McCormick went to the doctor feeling sluggish.

Just a few days later, McCormick was diagnosed with acute myeloid leukemia, a type of cancer that attacks the bone marrow.

McCormick has already started an aggressive chemotherapy treatment.

After learning about the diagnosis, the Bishop Kelly community set up a GoFuneMe page to help McCormick pay for building medical costs. In one day, McCormick's GoFundMe page reached its initial goal of $15,000.

As of Wednesday afternoon, that number has surpassed $20,000.

After hearing of McCormick's diagnosis, Kuna High School, an arch rival of the Knights, decided to step in.

"May we all find ourselves in a position that we are not needing this kind of aid; but if we do, knowing we have a community behind us, whether they wear our logo or not," Kuna High said in a press release.

On Friday, April 8, Kuna baseball and softball host Bishop Kelly for conference play. Fans are encouraged to wear orange, the color of McCormick's favorite baseball team, the San Francisco Giants.

All proceeds will be donated to the "McCormick Strong" fundraiser.
