Derek Luke Playing A Howling Commando In Captain America?

BigShinyRobot is claiming they've seen the Captain America poster which features Derek Luke. The actor has never been mentioned as being apart of the cast so it seems like a bit of reveal. CHUD talked to director Kevin Feige who confirmed to them that Gabe Jones would be in the film.

Gabe is a member of The Howling Commandos and would eventually be an important part of SHIELD. Other Howlers such as Dum Dum Dugan (Neal McDonough) and Union Jack/Pinkerton (JJ Feild) have been confirmed. It's also possible the role could be Isiah Bradley or even Sam Wilson (Falcon). I guess we'll know for sure if this is true as it's likely the group will be shown in the trailer.
