Frank Ross has signed a new one-year deal with Aberdeen.
The homegrown midfielder, who has made 14 appearances for the first team, also has an option for a further year.
Ross spent the latter part of the 2017-18 campaign on loan to Championship side Morton and scored his only goal for the Dons against Rangers.
He played in the 1-1 draw with Hibernian back in August but battled a troublesome back injury for the majority of this season.
The 21-year-old, who made his debut against Dundee in 2015, follows Joe Lewis, Andy Considine and Shay Logan in committing their immediate future to the Dons.
