Andrews was named League Two player of the season as he captained the Dons to the title and Johnstone's Paint Trophy.
Former Dons manager Paul Ince has now taken over at Ewood Park.
Di Matteo said: "There has been some contact there but there is nothing official to announce yet.
"Of course I'd love to keep my captain. He is an important player who had a fantastic season last year but we will see."
