Avengers: Endgame featured a cameo from Brock Rumlow/Crossbones (Frank Grillo) in a sequence that saw Captain America and the rest of Earth's Mightiest Heroes travelling through time. Although the villain blew himself up in Captain America: Civil War, Grillo has revealed he has a lot more movies left on his contract.
When asked by ComicBook.com about his future in the Marvel Cinematic Universe, Grillo replied, "You know what? I got five more movies that I'm obligated to do for Marvel if they ever call me. So who knows, man? Maybe I'll be Captain America after Mackie. I'll be a middle-aged Captain America. A middle-aged, Italian, Captain America. Think about that."
Grillo first appeared as Crossbones in 2014's Captain America: The Winter Soldier. He went on to reprise the role in two subsequent films. However, it remains to be seen if Marvel Studios will actually have Grillo return for five more films to finish out his contract, as his death would certainly complicate matters in that regard. Plus, with Chris Evans retired from the role of Steve Rogers/Captain America, there may not be a place for Grillo in the MCU's future, though anything is possible.
