What’s theoretically possible, I suppose, is that a pass goes through someone’s hands, and someone else intercepts it, then returns it for a touchdown — one team would say that the receiver had control of the ball long enough for it to be a touchdown, and the other would say that it was an incomplete pass up until the point it was intercepted.

And, of course, Rich’s niggling answer would be correct in the NFL case, too.

Also, I suppose that someone in the NBA could very quickly rebound an attempted three-pointer off the rim, make a full-court shot from that spot, and get called for goal-tending.

I don’t know NBA review rules well enough to be able to tell you if that sort of a thing is reviewable or not, and I find it unlikely that the whistle wouldn’t have been blown by the time the rebounding player got the shot off.

Upon further review, I will have to dispute your answer

The scenario: The game between Pittsburgh and Toronto is tied 2-2 and Tyler Kennedy comes down and shoots what looks like a goal but the ref waives it off and says no goal and Toronto comes down the other way and Jason Blake (who always freakin scores against the penguins) blows one by Marc-Andre Fleury. Before the puck is dropped for the Blake goal, upstairs (ie the NHL Office) calls in and says the Kennedy shot is under review. If you were to ask the ref at that time - he should tell you the score is 3-2 Toronto - because that is reflective of the calls that were made by the officials on the ice. (If he’s a nice guy he may tell you “However there is a review going on that may change the score”).

The reason for this is because what upstairs is doing will reverse the
call, until that moment that the call is officially reversed what is
called on the ice is “official”. A referee on the ice is instructed to
always make a call one way or the other (goal/no goal) and that is
considered official unless it has been reversed - but until it is
reversed - what the referee called is official.

Two main reasons for this: 1) The referee is talking to the head office
and the phone call drops (you’ve seen the cingular ads - a drop call
makes a world of difference ;)) - if communication can’t be restored in
a reasonable amount of time (I believe it’s at the refs discretion)what
was called on the ice stands. 2) When the replay is inconclusive (or
the video replay is inaccessible) what was called on the ice by the
referee stands.

If you’re ever at a game where this happens (or watch it on tv) the home team is instructed to put the score on the board — In the case above while the call was being reviewed the score board at Mellon Arena would show 3-2 Toronto and then once the referee got notification from the head office they would then switch the scoreboard to 3-2 Pittsburgh.

Good puzzle!
