Bayern new signing Serdar Tasci suffered a head injury in training and was forced to miss his own unveiling.
Tasci joined Bayern Munich on loan from Spartak Moscow, as they’re looking for defensive cover following the injury exit of Boateng and Martinez.
Matthias Sammer attended the unveiling with a jersey bearing Tasci’s name and number, without the player present.
Sammer did not completely rule Tasci out of featuring in Saturday’s match at Bayer Leverkusen, however.
“In training he had a collision with his head. Maybe it is a mild concussion, Sammer said.
“He may turn out [in] two or three days, that’s not so bad.
“He is an experienced player who wants to grow into an important role for the national team.
“A player who brings many qualities – he is 28 but I hope he will seize this opportunity.
“Serdar is really looking forward to the experience and can help us with his character and his style of play.
“The situation was clear for everyone that we were in a difficult situation after Martinez’s injury, so we decided to sign a new centre-back.”
Sammer moved to deny speculation that Medhi Benatia was in line to rejoin former club Roma before Boateng’s injury forced a rethink.
“We didn’t want to sell Benatia,” he said. “This is utter nonsense. The media claiming that we wanted to are lying.
“Only an insane club would think about this.”
