The Bavarian powerhouse said 18-year-old Musiala suffered a capsule injury in his right ankle and Ulreich suffered a partial inner ligament injury in his right knee joint.
Bayern did not say how long either player will be out.
While Ulreich had made only one appearance in the German Cup for Bayern this season, Musiala made a significant impact in the opening games with four goals and four assists in six appearances. He didn't play a full game in any and was given a rest for Bayern's 7-0 rout of Bochum on Saturday.
Musiala has also made eight appearances for Germany.
The Bundesliga leaders face promoted Greuther Fürth on Friday.
