That's correct but the ATR was published in 1998 and written almost 2 years before. The new training that has been given in the past 2 years is not what it says in the ATR, a new version is soon to be published. If you look at the pro web page
http://www.ussoccer-data.com you will find a button that is titled Topics. Click Topics and then scroll down until you see something titled Misconduct and Showing of Cards. Click on that, it is in PDf format and you will need Adobe Acrobat to read. IF you can't download or read I will be Gladd to post this memo from USSF on this site.
Let me know
