I just read this at http://insidetv.ew.com/2011/10/28/blue-bloods-world-series/:
CBS is outta here. With the World Series going into a seventh game tonight, CBS is pulling its original episodes of CSI: NY, Blue Bloods and brace yourself A Gifted Man. Repeats will air instead the Gifted Man pilot, then encores of CSI: NY and CSI: Miami (no Blue Bloods).
Your right about their explanation for why. Now we’ll see if they run it next week.
