I apologize to Joe Landreneau for misspelling his name in the prior message. Also,I meant to say that a player in possession of the ball can be tackled from behind in a legal fashion.The tackling player could conceivably get all ball first without any contact with the player in possession. Is this correct? If there is contact with the player first and the player was on a breakaway, I thought the call was an automatic red card but this may be in the ref's discretion. There should be a yellow card for this foul at the very least but I have seen this twice this year with no cards being given although the foul was called and a direct kick awarded. If someone would clarify this, I would be grateful.
