  • The Russo Brothers, the directors of Marvel's "Avengers: Infinity War", changed their Twitter profile picture to Bucky Barnes holding Captain America's shield.
  • Fans are speculating what this could mean for Captain America, who's played by Chris Evans.
  • The Russos could be misleading fans – but there's also reason to believe Marvel might kill off the character.

The Russo Brothers, the directors of "Avengers: Infinity War," changed their Twitter profile picture on Monday, and fans think it could mean bad things for Chris Evans as Captain America.

The picture is a piece of art depicting Captain America's best friend Bucky Barnes — played by Sebastian Stan in the movie — holding Captain America's shield, rather than Captain America himself, Steve Rogers (played by Evans).

The only caption is "#NewProfilePic," leaving fans to speculate on Twitter what this could mean for Captain America's fate in "Avengers: Infinity War" — and also panic.

The tweet has over 1,000 comments ranging in emotions, from scared to sad. Many fans are afraid that the picture means doom for Captain America; some think if Captain America dies, then Sam Wilson/The Falcon (played by Anthony Mackie) should replace him; and some are just upset about potential spoilers.

Considering the Russo Brothers recently posted a message to fans on Twitter asking them to refrain from spoiling the movie after they see it, it's hard to believe they would so heavily tease such a huge spoiler like Captain America's death in "Avengers: Infinity War." So this new profile picture could just be a fun misdirection on their part. 

But it wouldn't be a stretch for Captain America to die, either. 

Evans has implied that he's ready to retire from the role and there's good reason to believe Marvel might kill him off. After Marvel's "Civil War" comic-event, Captain America died and Barnes took his place until Rogers returned (because nobody stays dead in comics).

The trailers for "Avengers: Infinity War" have certainly been ominous, and its characters look like they're in plenty of trouble. But Captain America's fate will be revealed later this month when the movie hits theaters on April 27.
