That's not Daryl. It's obviously Ben from the Tyreese group. Same clothes, same hair, same size.
Taking a second look, it appears:
The person in the right foreground seems to be Daryl himself, as the leather jacket and color of the shirt looks like the clothes he's sported since it was introduced in S2, and throughout this season. I do not think that short piece of leather is the vest worn by Phillip. Something tells me this is likely the big scene where Daryl has to kill Merle--essentially a replay of the S2 Rick vs. Shane finale.
