If you see a player from one team blatantly flip off a player from the opposing team, do you have a foul? Would it be 15 yards only or does he get tossed?

This action is not a personal foul.
It would be an unsportmanlike foul.

Both are 15 yarders, but multiple UCs will get you tossed.
Yes, you can get tossed for a single personal foul, but it better be one of the serious types before you do that. Throwing a punch is one of those.

Thanks, Theisey. I saw this in a scrimmage and told the two of them to knock it off. Since I am working the middle this year, I thought I'd better be ready for it in a game.

36 years "in the middle" here--
if I saw that I'd probably ask that
player--
"what's that supposed to mean ?"
and follow up with something like--
"that has nothing to do with playing football"
or
"football is blocking and tackling and not flipping "the bird" "
talk to the kids !!
it works 99.9% of the time and you won't have
to get your flag dirty !!

theisey,

an unsportsmanlike foul is a non-contact foul, in this situation it is not usportsmanlike, you are wrong. it could be a flagrant foul or just a personal foul.

I thought he meant flip off, like giving the middle finger to the other team...????? LOL

What are you talking about? Flipping someone off is a noncontact foul.

i apologize, i thought he flipped the guy, like slammed him. i miss read this. i am sorry.

I agre3e the wording is confusing...LOL

It would be best then to go back to your post and delete it. Very easy to do.

thanks theisey, you are so smart.

What's that comment supposed to mean? I certinaly did not take offense to your original post calling my statement as being wrong. But I do take offense your recent one. Stop being a jerk and act like a football official.

It's common to go back and either DELETE a post or to at least edit it to clear up an misunderstanding.
