Lines has found himself down the pecking order at Hillsborough this season, making just six appearances.
The former Bristol Rovers man is keen to be playing regularly and is happy to go out on loan in search of first-team football.
A number of clubs are thought to have expressed an interest in Lines, but MK Dons are poised to win the race for his signature.
Dons boss Karl Robinson is a big fan of the midfielder and sees him as a key addition to his squad as he looks to maintain their promotion push.
