Burki will undergo surgery at Knappschaft hospital in Brackel, meaning that he will be sidelined for up to eight weeks.
The 26-year-old Swiss keeper hurt his hand in Dortmund's 1-0 triumph at home against Bundesliga champions Bayern on Saturday.
It was his third clean sheet in four games in all competitions as Thomas Tuchel's side jumped up to third in the table, three points behind second-placed Bayern and six adrift of surprise leaders RB Leipzig.
Veteran Roman Weidenfeller will stand in for Burki, starting against Legia Warsaw in Tuesday's Champions League clash.
