Jason is best friends with Tim Riggins, his fullback. They have known each other, and Jason's (ex) girlfriend Lyla Garrity, since middle school. Throughout the show they are seen supporting each other almost unconditionally and bailing one another out of trouble. Prior to his injury, Jason was dating Lyla Garrity, who was then captain of the cheerleading team, and had an on-off relationship and brief engagement before circumstances led them to break up for good. Their friendship is tested in Season 1 when Tim sleeps with Lyla to cope with his feelings of guilt and self-hatred as he felt he could have prevented Jason's injury by tackling the defensive player before Jason did. In Season 2, they are on speaking terms and still good friends.
