New Delhi, March 17 -- Bayern Munich has lost an appeal against Luis Diaz's one-game ban for a sending-off in the Bundesliga, even though the referee admitted his decision wasn't the right call.

Diaz was sent off after a second yellow card for diving in Bayern's 1-1 draw with Bayer Leverkusen on Saturday, in which he also scored Bayern's only goal.

As a yellow card offense, it wasn't subject to video review. After viewing a replay in a postgame TV interview with Sky Sport Germany, Christian Dingert said he had missed contact between Diaz and goalkeeper Janis Blaswich and added: "The second yellow card is very harsh and when I see the images now, I wouldn't give it that way any more."

That wasn't enough for the German soccer association...
