The Huntsville School Board accepted Grissom football coach Keith Henderson's resignation Tuesday morning.
Henderson was arrested and charged with driving under the influence in August, less than two weeks before football season began.
Officials said Henderson was apparently trying to push tractor tires off the playing field by using a pickup truck and ended up getting the truck stuck. According to school officials, Henderson's blood alcohol content was .12.
Henderson was placed on paid administrative leave after the arrest. His resignation will go into effect on December 25. He will remain on administrative leave until that time.
