KARNS CITY, Pa. — (WPXI) – The family of the Karns City High School quarterback who collapsed on the field last week posted an update on his health. The Karns City Gremlin Football page shared the update from Mason Martin’s family. In it, they say within the last 24 hours, he has moved his arms, his eyes slightly reacted to light and he’s moved his legs when pinched. They say his chest tube has also been removed. “This is the first positive step in an extremely long journey,” the post said. “The prayer vigils held at the hospital and at Karns City have overwhelmed us with joy and support.” (PHOTO; Holly Mead Photography)
