Morton dealt Hibernian's title hopes a major blow with a 3-0 win in a rearranged game at Easter Road on Wednesday night.
The victory ended Hibs’ unbeaten home record in the Ladbrokes Championship this season and moved Jim Duffy's men to within a point of the top four.
Thomas O'Ware gave the visitors the lead towards the end of the first half and on-loan Birmingham City striker Denny Johnstone doubled their advantage six minutes after the interval.
Ross Forbes sealed the win in 63 minutes as Morton climbed to fifth in the table, leaving Alan Stubbs' side eight points behind leaders Rangers.
