"Mr. Seaman started running at him," the boy said. "He tackled him to the ground. We were all hiding in the back of a classroom behind some desks, then (Seaman) was yelling to call 911, to get out of the building as fast as we could, so we ran (out)."
In a statement Friday evening, Seaman, who teaches seventh grade and coaches football, thanked first responders for the "immediate action and care."
He added, "I want to let everyone know that I was injured but am doing great. To all the students, you are all wonderful and I thank you for your support. You are the reason I teach."
