An early concept art illustration for Avengers: Infinity War features a very similar Captain America, though with one glaring difference. Had the concept made its way into the movie, Captain America's costume would have been gone.
In a post to his Twitter account, character designer and concept artist for Marvel Studios, Ryan Meinerding, shared an initial concept for Avengers: Infinity War in which Steve Rogers had left the Captain America costume behind. "This was an initial idea for #CaptainAmerica for #InfinityWar. We tried a lot of different things for him and one of them was that he had left his Cap costume totally behind. #MarvelStudios," the artist wrote.

In the lead up to the events of Avengers: Infinity War, Steve Rogers is a fugitive along with Falcon, Black Widow, Scarlet Witch and Vision. While not quite an exact representation of his alternate identity in the comics, Nomad, Infinity War Steve Rogers embodies the spirit of this alternate identity. Sporting a blacked-out version of his suit from Captain America: The Winter Soldier and having given up his Vibranium shield following his final battle with Tony Stark in Captain America: Civil War, Rogers has effectively left the Captain America title behind when he first appears in Infinity War. Meinerding's initial concept would have made this all the more evident.
