'Bones' star John Francis Daley will guest star on the show's spinoff, 'The Finder.'

According to TVLine, the 'Freaks and Geeks' veteran will play his 'Bones' character, Sweets, when the show debuts midseason.

"Who is more qualified to examine [Geoff Stults'] brain damaged paranoid finder than Sweets?" Stephen Nathan, 'Bones' executive producer, told TVLine.

Daley is expected to be one of many 'Bones' actors to guest star on the new series. David Boreanaz has signed on to direct an episode of the new show.

In advance of this afternoons Upfront presentation in New York, Fox announced its fall 2011 TV schedule this morning. There aren't any big surprises, aside from the 'Bones' spinoff 'Finder' getting its debut at midseason instead of this fall as a contingency plan for Emily Deschanel's pregnancy like many predicted.

The long-delayed 'Terra Nova' finally gets its official debut this fall, with the Steven Spielberg-produced dinosaur show airing Monday nights at 8PM before 'House.' 'The X Factor' takes over 'American Idol''s time slot, and will help launch a new comedy on Wednesday nights.

Another interesting tidbit to note: 'America's Most Wanted' has been discontinued as a regular TV series; after 23 years Fox has decided to bring back the show in the form of occasional specials.
