Wilson, 23 was sounded out of the Robions squad upon the arrival of Derek McInnes as manager and only managed 21 Championship games last season as the club only just avoided relegation to League One.
It is believed that Championship rivals Derby County are keeping tabs on Wilson's situation, along with League One duo Coventry City and Sheffield United.
The Sky Blues are in need of fresh recruits at the back after Martin Cranie decided to leave and Richard Keogh was the subject of a failed bid from Bristol City.
