Pierre-Emerick Aubameyang has not testified as planned in the trial for the attack on the Borussia Dortmund team bus last April because of illness.
Aubameyang, who according to Sky sources is on the verge of joining Premier League side Arsenal in a £60m transfer, had been due to give evidence to a German court on Monday.
Lawyer Alfons Becker was quoted in the German paper Frankfurter Allgemeine, saying; "He will not testify today because he is ill."
Aubameyang's team-mate Marc Bartra, who was injured in the attack suffering an open fracture of a forearm, did prepare a statement which was read out in court by his lawyer.
The Spaniard said: "I was scared to death. I feared I would never see my family again… when I remember the attack, it makes me feel unwell."
A 28-year-old known as Sergej W, is accused of the attempted murder of 28 members of Borussia Dortmund on April 11 last year but says he did not want, or intend, to kill anyone.
Judges are currently arranging further dates to hear personal testimony from players who were on the bus, and have still to decide whether they will set another date for Aubameyang's evidence, or fine him for not appearing.
