Just days prior to his team's Saturday match against Wolfsburg, Herrlich left the team's hotel to buy toothpaste at a local supermarket, the team said in a statement.
"I made a mistake by leaving the hotel," Herrlich said in a statement, per the BBC. "Even though I have followed all hygiene measures both when leaving the hotel and otherwise, I cannot undo this. In this situation, I was not able to act as a role model for my team and the public. I will therefore be consistent and stand by my mistake. Because of this misconduct, I will not be leading the training [on Friday] and will not be in charge of the team against Wolfsburg on Saturday."
Saturday's match would have been Herrlich's first as the club's manager, as he was appointed in mid-March, just days before the league's matches were postponed amid the coronavirus pandemic.
