Rowe is entering the final year of his contract and will be placed on the transfer list in line with club policy if he does not agree a new deal.
Ferguson told the Peterborough Telegraph: "There is a good chance Tommy could move on.
"Tommy is the sort of player who will not cause us a problem, but we would be silly to let his contract run down and lose him for nothing at the end of next season."
Ferguson has offered new contracts to midfielder Grant McCann and defender Mark Little.
The pair were made available for transfer last summer, but went on to have impressive seasons as Peterborough were relegated from the Championship with a record points tally of 54.
Tyrone Barnett, who cost Posh a club record £1.1 million 15 months ago, fellow strikers Emile Sinclair and Nicky Ajose and midfielder Danny Kearns have all been put on the transfer list.
