Borussia Dortmund defender Marc Bartra will be out for about four weeks because of the injury sustained in the bomb attack on the team bus.

Coach Thomas Tuchel said on Thursday that "it looks like Marc Bartra will return to the team in four weeks. He'd like to play now already."

Bartra was hit by shrapnel as three explosions hit the bus on Tuesday as it left the team hotel for Dortmund's Champions League quarterfinal match against Monaco.

The Spaniard was taken to hospital and had surgery on a broken bone in his wrist. After the operation, Bartra posted an Instagram photo of himself making a thumbs-up gesture with his left hand. He had a bandage wrapped around his right arm, and a smaller bandage around his left wrist.
