I first have to start with a caveat: I didn't see the play so I don't know if the report I saw is actually correct or not. If any one saw it please correct me.
The situation in Oak v. BUF.
Oakland to punt. Buffalo roughs the kicker. during the dead ball period, before the chains were set, the OAK punter picks up the flag and acts the fool, (using a prop) getting an Unsportsmanlike penalty.
In this article
http://www.cbssports.com/nfl/news/look-raiders-punter-calls-out-bills-player-on-twitter-for-being-a-snitch/?linkId=31982102 it says
"Although King (the Oakland punter) was hit with a 15-yard penalty on the play, it didn't really hurt the Raiders because the flag game after the play. Since the Bills were penalized first, the Raiders got a first down. After that penalty was enforced, King's penalty was added and the Raiders got the ball at their own 32-yard line with a fresh set of downs, only they were facing first-and-25 instead of first-and-10 because of King's penalty."
Why would that be 1st and 25? I assumed it would still be 1st and 10, as the new line to gain had not yet been established (the chains had not been set when the UNS foul occurred.)
Am I missing something?
