At the end of Captain America: Civil War, Steve Rogers left his shield with Iron Man and walked away from the Avengers. According to the film's directors the Russo Brothers, that wasn't a bluff - Steve is actually retired from being Cap.
"I think him dropping that shield is him letting go of that identity," Joe Russo told The Huffington Post. "It's him admitting that certainly the identity of Captain America was in conflict with the very personal choice he was making."
That doesn't mean that Steve won't be back in action as Captain America by the end of the Russos' next Marvel film, Avengers: Infinity War. It some ways its reminscient of Tony Stark saying he was no longer Iron Man at the end of Iron Man 3, only to change his mind for the next Avengers movie.
For Chris Evans' Steve Rogers however, it's also possible he could take on a different codename, as Rogers has used several over the years in comic books.
Captain America: Civil War is due out on home video September 13.
