Midfielder Lars Stindl has been suspended for a Bundesliga match after pointing out he should be banned for getting five yellow cards this season.
The 24-year-old Stindl kept count better than German football authorities who failed to register an earlier booking.
When Stindl was cautioned Saturday in a 5-0 loss against leader Bayern Munich, he told his club it should trigger a one-match ban.
Stindl says he wasn't tempted to exploit the official error, asking: "Why should we hide something?"
Hannover published the story on its website with the message: "Hats off, Lars!"
Coach Mirko Slomka praises Stindl as "an extremely fair sportsman" — who will watch the home match against struggling Greuther Fuerth from the sidelines.
