The 18-year-old England youth international recently signed a new two-year contract with parent club Fulham, although he has yet to make his first-team debut.
And after penning a one-month loan deal with Dons on Monday, Marsh-Brown could make his bow in the League One clash at the Memorial Stadium.
French goalkeeper Willy Gueret, however, will not feature as he is poised to join Kettering after his Dons contract was cancelled by mutual consent.
Gueret was first-choice goalkeeper and a regular starter last season but has failed to appear for the first team this time around following the arrival of David Martin from Liverpool last July.
Midfielder Mark Carrington also plays no part having left Dons by mutual consent on Tuesday, subsequently agreeing a deal to join Scottish Premier League club Hamilton as a free agent.
