What does it mean if a football card is an "insert"?
463135
Insert is a card that is randomly placed in packs.  A sport card company will put 1 card in a box and that means 1 in like 36 packs.  That card is then an insert.  Sometimes they do 1 per case or even less and the inserts become quite rare - they become chase cards.  This is used to help entice people into 'chasing' the card and buying more packs, boxes or cases.

It belongs to a category called "marking" the card. Marking also includes placing an ink, lipstick  mark on the card.  Oh, it's also called "cheating"!!!!!

when he gets a red card or 2 yellows in the same game. 2 yellows equal a red. Cards are given at the discretion of the referee. If you tackle too hard, do something unsportsmanlike, or malicious. Slide tackling someone without contacting the ball is a card, stuff like that. Punching someone, elbowing, arguing etc.

If it is a team fine, then it goes to the Company or owner of the team to be used as management of that company (team) in repairs, uniforms, or just to help the team. If it is a league fine, then I believe that they say it goes to the NFL or whatever league for the betterment of the league.  Prob still goes into the commish's pocket, but for their sake, I am sure they would say that it is donated or used for advertising or some crap like that.

Yellow = warning (2 = red card)\n\nRed = sent off\n\nIn tournaments if you get more than (say) 1 yellow card or a single red card you can be banned for a few matches ... in league matches a certain amount will also lead to a match ban.\n\nIt could also mean "your agent is on the phone with an outrageous deal to wear silly coloured shoes" but that might just be David Beckam.

In addition to cotapaxi's excellent info, I would add that they are usually short printed or limited printed insert cards that are more valuable than the standard card of a particular player

Depends on the Ref.\n\nIn the group stage, two inconsecutive yellows = miss the next game. Two yellows in the same game = miss the rest of the game and group stage. Yellow cards don't carry over in the elimination rounds. Two yellow cards in the same game in the elimination round = sit out the rest of the game and possibly tournament.

Follow the default rules, don't try to make things interesting for the first time.  I have seen people changing rules so it becomes extremely favor to RBs, and the commissioner doesn't even know.  Be ware of this weird situation.

Depends on if it's in good condition or not. And Topps cards weren't the greatest either, so it's hard to tell. Look it up somewhere on a sports card website.

In Fantasy Football, it means Passes Defended. Hope that helps.

The yellow card is a penalty for committing a brutal or tactical foul. If a player gets 2 yellow cards he is sent of the field so a card is a warning by the referee for the player.
