Bayern Munich could face punishment from German football authorities after playing part of their Bundesliga match against Freiburg with 12 men on Saturday.
The Bavarians were a man up for around nine seconds late in the game, as they ran out 4-1 winners to stay comfortably top of the table.
But Saturday's victory has quickly become shrouded in controversy after a mix-up with their substitutes. In the 85th minute, manager Julian Nagelsmann sent on Niklas Sule and Marcel Sabitzer to see out the game.
