After beloitpiper's post, I hunted a little and then read that the April 16 show will be the last aired.

"Over at NBC, net will yank Paul Haggis-Bobby Moresco drama "The Black Donnellys" from its posh Monday-night perch in order to make room for its new reality take on "Wedding Crashers."

"Donnellys" had been slated to air most of its 13-seg run at 10 p.m. Mondays. Assuming NBC doesn't pull the plug sooner, "Donnellys" will end April 16, getting to air just eight episodes on Mondays -- with only two of those segs airing behind original episodes of "Heroes.""

But wait, that only means that they won't be on Mondays anymore -- some researcher I turned out to be.
