NBC had tonight's game in HD, so I would guess yes. I'm pretty sure that for the games the network's A teams do (in CBS's case it would be Nance-Simms), HD is always available.
Conflicting info on whether Friday's game is in HD...
CBS's website does not show that the game is in HD, and when I used my DirecTV program guide, it did not show the HD symbol in the guide next to the game listing.
