• Fox has unaired episodes of "Back to You," "'Til Death" and "Bones" coming between now and April.

• Fox has several episodes of several midseason shows. "Unhitched" debuts on March 2; "New Amsterdam" on March 4; "The Return of Jezebel James" on March 14; and "Canterbury's Law" on April 14.

NBC: "ER," "Law & Order," "Law & Order: SVU," "My Name Is Earl," "The Office" and "30 Rock" are expected to go back into production. All will apparently air new episodes this season; some may be held for the fall.

(This may be the final season for "ER," so that's another complication.)

• "Chuck" and "Life" will probably also go back to work but may not return to the air until the fall.

• "Heroes" will return in the fall but may not air any new episodes until then.

• The fate of "Friday Night Lights" is undetermined.

• New episodes of "Las Vegas," "Lipstick Jungle," "Medium" and "Law & Order" are currently airing.

• The midseason show "quarterlife" is set to debut on Feb. 26.

• "Scrubs" also has new episodes already completed that will air this season. This is the show's final season, but whether the series finale will ever be produced is up in the air.
