Borussia Dortmund will be without Marco Reus for Wednesday's rearranged Champions League clash with Monaco at Signal Iduna Park.
The Germany international has failed to recover from a thigh injury and has been left out of the squad for the first leg of the quarter-final.
Reus suffered a muscle tear in the 6-2 Bundesliga win over Bayer Leverkusen on March 4 and has missed Dortmund's last seven games, including the second leg of the last-16 win over Benfica.
Head coach Thomas Tuchel had hoped to have Reus available after he trained with the squad on Monday, but he has decided not to risk a further setback for the 27-year-old, who has only managed 15 appearances in all competitions this season.
The match was rescheduled after the Dortmund team bus was caught up in a bomb blast approximately an hour before the planned kick-off time on Tuesday, leaving defender Marc Bartra requiring surgery on a broken wrist.
Dortmund's players warmed up for the match wearing shirts showing support for Bartra.
