The 22-year-old defender joined the club from Second Division Mainz in the summer but must now sit on the sidelines for an extended period before making his Bremen bow.
"That's a bitter blow for him and the whole team," said coach Thomas Schaaf.
"Manuel looked on the verge of making the first team, but we will do all we can to support him."
Friedrich will have medical tests over the weekend to determine how serious the injury is.
