Borussia Dortmund coach Thomas Tuchel says defender Marc Bartra will be sidelined for about four weeks following injuries suffered in Tuesday's bomb attack on the team bus.

Meanwhile Germany international Marco Reus is set to make his comeback in Saturday's Bundesliga game at home to Eintracht Frankfurt, Tuchel said in Dortmund.

Spanish defender Bartra has undergone surgery following a fracture in his right wrist and injuries to his arm in Tuesday's explosions.

Reus, 27, has recovered from a thigh muscle tear against Bayer Leverkusen on March 4. He has been back in training since Sunday and will play against Frankfurt, Tuchel said.
