Morton goalkeeper Derek Gaston has signed a new contract that will keep him at the Greenock club until the summer of 2018.
The 28-year-old has been at Cappielow since joining from Albion Rovers in 2012 and was a key player as Jim Duffy's men clinched the League 1 title in 2014/15.
Morton are sixth in the Ladbrokes Championship as they prepare to travel to Falkirk on Saturday.
