Cowboys/Steelers question

[JasonTX]

One official has the feet and the other official is looking at the ball. If this is the play I'm thinking of they ruled it a catch after replay because he got three feet in. Anyhow the official that seen the ball bobble came in and said incomplete which is proper. Also, if the first official who ruled catch would have ruled he would have caught it if he wasn't pushed out he would have given the "push out" signal and the play couldn't have been reviewed. A "push out" is non reviewable.
