JENKS, Oklahoma - Jenks head football coach Allan Trimble was diagnosed with ALS last week, a disease that affects nerve cells in the brain and the spinal cord.

Trimble will undergo a management program, but doctors believe that he will make it through coaching the upcoming season.

Trimble told News On 6 sports reporter Harold Kuntz that he’s optimistic.

Jenks Public Schools released the following statement:

"It is heartbreaking and shocking to learn of Allan Trimble’s diagnosis with ALS.
