Scunthorpe’s second successive relegation was confirmed after they fell to a 2-0 home defeat against Oldham in the National League.
The Iron, who were relegated from the Football League along with Latics last season, will play in National League North next season.
The visitors opened the scoring five minutes before half-time through Devarn Green.
Scunthorpe almost hit back immediately when the ball fell to Will Smith inside the box after a great passing move but his effort from six yards was well saved by Magnus Norman.
Oldham were awarded a penalty when Bassala Sambou attempted to get on the end of a long ball forward and goalkeeper Tom Billson rushed out and brought him down in the area.
Sambou picked himself up and tucked the penalty away to double Latics’ lead and end a run of six games without victory, condemning the home side to the drop in the process.
