Frank Grillo expected to return to Captain America 3 as Crossbones

At the End of Captain America: Winter Soldier, Frank Grillo's character Rumlow was willed to the hospital after the character taken a serious hit. Frank Grillo is said to be expected to reprise his role in Captain America 3 as Crossbones, Rumlow's alter ego. 
People were really happy about this when Frank Grillo was first casted for the role of Rumlow. I think people are finally getting their wish.
“I would say he’s learning to be Crossbones in a way. With Frank Grillo, he’s a great actor. When he wants to, he can turn on this light that makes you think, “He’s out of his mind,” and I think somewhere down the line he will push past the R rating. He doesn’t in this movie, mainly because it’s PG-13, what are we going to do past an R? We can’t go past the PG-13. Taste of things to come? I don’t know if I’m leaking…”
“Very early on the Russos said, ‘Look, this is an origin film for this character. We’re gonna discover who this is and this is a big movie with a lot of moving parts, but we’re gonna discover you in this film and, you know, here’s the information about who Brock Rumlow turns into and blah, blah, blah.’ And so we’ve had multiple discussions about what comes after that, that thing. So, you know, it’s obvious Rumlow is covered in rubble and burned to crisp at the end, but you see he’s still there. They don’t do that for no reason.”
