DORTMUND, Germany (AP) — The Latest on attack on Borussia Dortmund team bus (all times local):
Borussia Dortmund fans have chanted the name of a defender who was wounded in the explosions that rocked their team's bus Tuesday night.
The chants came Wednesday night at the start of the delayed Champions League quarterfinal against Monaco.
Central defender Marc Bartra was missing from Dortmund's lineup after undergoing surgery for injuries to his wrist and arm caused when three explosions shattered a window of the team bus. The team says he will be out for several weeks.
After reading out the team list, the announcer at Dortmund's stadium made the unusual move of announcing a player who was not playing. He shouted: "Our number five, Marc!" and the packed stadium roared the defender's surname: "Bartra!" three times in response.
Dortmund players also paid tribute to Bartra during their warmups, wearing T-shirts emblazoned with his picture and the text "A lot of strength — we are with you."
Borussia Dortmund players have gotten a rousing ovation as they took to the pitch in their tracksuits to check out conditions more than an hour before kickoff in their Champions League quarterfinal against Monaco.
Applause rang around the BVB Dortmund stadium on Wednesday as some players emerged onto the turf less than 24 hours after three explosives detonated near their bus, injuring a defender and forcing the postponement of the first leg of Dortmund's match against Monaco.
Fans of Monaco, grouped together in a corner of the stadium, also chanted support for Dortmund. The move drew more applause from German fans and the players.
The mutual applause was an indication of how the attack has united both teams' fans. Some Monaco supporters stayed at the homes of strangers in Dortmund after the match initially scheduled for Tuesday was hastily pushed back a day following the attack on the bus.
Borussia Dortmund defender Marc Bartra has taken to Instagram to assure fans that he's "doing much better" after being hurt in the attack on his team's bus.
After an operation, Bartra on Wednesday posted a photo of himself with a bandage wrapped around much of his right arm, and a smaller bandage around his left wrist. He made a thumbs-up gesture with his left hand.
The 26-year-old from Spain wrote: "All my strength to my team mates, supporters and fans and to @bvb09 for tonight's match!" He thanked "everybody for all your support and your messages!"
Bartra's wrist and arm were wounded when three explosions near the team bus broke a window on Tuesday evening. Dortmund's Champions League quarterfinal match against Monaco was rescheduled for Wednesday.

The club said the 26-year-old will watch the Champions League quarterfinal match between his team and Monaco on television Wednesday evening and "is keeping his fingers crossed for his colleagues."

German prosecutors say a letter found near the scene of the Dortmund team bus blasts suggests a possible Islamic extremist motive for the attack, and one suspect has been taken into custody.
Frauke Koehler, a spokeswoman for federal prosecutors, said Wednesday that two suspects from the "Islamist spectrum" have become the focus of the Dortmund investigation. She says at a news conference that both of their apartments were searched and one of them has been detained.
She says the letter at the attack site demands the withdrawal of German Tornado reconnaissance jets from Turkey and the closure of the United States' Ramstein Air Base in Germany. She said authorities are still evaluating its credibility.
Koehler says authorities have "significant doubts" about another claim online giving a left-wing extremist motive for the attack.
A German official says that authorities are still "in the dark" about the motive for the attack on Borussia Dortmund's team bus and don't know whether one or several perpetrators were responsible.
Authorities are investigating a letter found near the site claiming responsibility. They haven't given details about it but Ralf Jaeger, the interior minister of North Rhine-Westphalia state, said it was "unusual" in that it didn't offer a clear motive. He said the letter could be genuine or "an attempt to lay a false trail."
Jaeger said Wednesday: "We are investigating in every direction ... the background is completely open and is in the dark."
Jaeger said: "It could be left-wing extremism or right-wing extremism. It could be the violent fan scene, it could be Islamic extremism."

Several German news media organizations are reporting that the note found after the bomb attack on the Borussia Dortmund soccer team uses radical Islamic rhetoric — but that police are not sure whether the note is genuine or an attempt to throw them off the track.
Die Welt newspaper and Sueddeutsche Zeitung reported online that the note made reference to Germany's participation in the military coalition opposed to Islamic State. German Tornado reconnaissance planes are taking part in a noncombat role. The papers said that experts on Islam were reviewing the note to try to establish its authenticity.
Meanwhile the dpa news agency reported that investigators were probing statements found on the web that indicated a left-wing motive to punish the club for allegedly not opposing racism strongly enough.
