The ABC series had been set to debut a full-length trailer for the 'Avengers' sequel, but the teaser leaked online earlier this week, reported Ace Showbiz.
Marvel Studios promptly brought forward the official release of a 2-minute teaser hours after the leak.
The Twitter account for 'Marvel's Agents of SHIELD' has now revealed that a new scene from 'Avengers: Age of Ultron' will air on Tuesday, rather than the trailer.
"On Tuesday's Marvel's #AgentsofSHIELD, see an EXCLUSIVE SCENE from Marvel's 'Avengers: Age of Ultron' on ABC!," the Marvel account posted.
The Marvel superheroes will come together to opposite the malevolent artificial intelligence known as Ultron (James Spader).
