I want to know the answer to the following question:
What occurs when a player in association football is shown a red penalty card?
All the background I'm provided with is that "Other teams that prominently feature red on their kits include A.C. Milan (nicknamed i rossoneri for their red and black shirts), AFC Ajax, Olympiacos, River Plate, Atlético Madrid, and Flamengo.". Is that enough to answer the question?
