Former Hearts winger Andrew Driver is training with Aberdeen, Dons boss Derek McInnes has confirmed.
The 27-year-old has been a free agent since leaving MLS outfit Houston Dynamo in November.
"Andy's someone we've invited in to train, he'll have a look at us and we'll have a look at him," McInnes told BBC Scotland.
"So while there's nothing definite there, the fact we brought him in means it is something we're interested in."
Driver played for Hearts for seven years between 2006 and 2013, featuring almost 150 times for the Tynecastle outfit.
He scored 18 goals for the Gorgie outfit.
