Hmmm.

Continuing on the "Where's our third jersey?" search...I may have just found it on the FSN preview here (which does not allow for embedding or screencaps as far as I can tell).

Go about one third of the way in to the video; when Stephen Weiss comes onscreen, look behind him on the far left.

We've heard previously that a light blue would be employed (why I have no idea). Could be a practice sweater but I'm betting against it. Look at it carefully: it has the standard RBK collar and what appears to be a white sleeve.

Maybe I'm seeing things, but I'm guessing we're looking at a strategically-placed new third-jersey, with the home-navy blue on it's right allowing for a tease.

Doesn't match this description from back in March, but that uni very well may have been a mockup.

I'm calling it real. Let the speculation begin...

BTW: the FSN preview show is tonight at 5pm.

UPDATE: Lotsa folks are saying it's studio lighting casting a glow on a home jersey, which it certainly appears may be the case.

UPDATE 2: False alarm, according to those in the know. Helluva way to spend a Saturday.
