I'd presume so as otherwise wouldn't that be too long of a break?
Although I guess its only two or three weeks & CBS may be concerned that viewers would rather watch the Olympics than their programs. I can't even remember here if we get repeats during Olympics
(but I do know that the channel which airs the NCISs doesn't have the rights to the Olympics, but at this point I'd presume CBS would need the rights for Ten to gain the rights since it owns Ten now)
