Steve Rogers is no longer Captain America but rather the Nomad in Avengers 3.

The Russos Brothers' the first Infinity War poster debuted at San Diego Comic-Con 2017 - but it's also a theory that has never been expressly confirmed... until now.

Anthony and Joe Russo posted a new image on their Instagram today (below) both confirming and teasing Chris Evans as the Nomad in Avengers: Infinity War. The cropped image was taken from a poster created by digital artist Tj Kiszka, who posted the full image on Instagram a week ago. Take a look:

For those that don't know, Nomad is a moniker that has been used by a variety of characters over the years in Marvel Comics, but it all started with Steve Rogers assuming the name in Captain America #180 way back in 1974, created by writer Steve Englehart and artist Sal Buscema. And just like what happened between the events of Civil War and Infinity War, in the comics, Steve picks up the name after he lets go of his life as Captain America - costume and all. Plus, Steve even has two new shields in Infinity War, something he got from his new, technologically-advanced friends in Wakanda.

While Marvel Cinematic Universe fans may have a difficult time letting go of Steve Rogers as Captain America, it's worth noting that he's not the done with Marvel after Avengers 4, as are plenty of other MCU superhero actors and actresses. The battle with Thanos marks the end of the MCU's first saga, so it's understandable for them to give Steve Rogers a way to move on from Captain America and leave the name behind for the next generation.
