NBC has pulled 20 Good Years from its schedule earlier than expected.

The sitcom, not picked up in the UK, will be replaced with an extended version of The Biggest Loser. It had been scheduled to disappear in any case a week later, with 30 Rock moving to Thursday nights.

NBC's decision to pull the show came as little surprise; the John Lithgow-starring comedy scraped a 4% share in adults 18-49 in its most recent outing.
