CBS has passed on the How I Met Your Mother spin-off How I Met Your Dad, after it was not included in the networks' 2014-2015 lineup announced earlier today.

Deadline reports that it's possible a last-minute agreement could be reached, since the network's option on the show expires later today, but even if a deal isn't reached, 20th Century Fox Television and the producers are expected to shop the spin-off around to other networks. There reportedly has been interest at other networks, with 20th Century Fox TV so confident in the pilot they expect it to get picked up elsewhere.

The site also reports that CBS had issued an offer to series creators Carter Bays, Craig Thomas and Emily Spivey to re-pilot the project, but they were not interested because the offer did not come with a series commitment. 20th Century Fox Television would have accepted the offer if it had a series commitment attached, which is what happened to CBS' The Odd Couple pilot that is being re-worked for a mid-season premiere.

Here's what CBS' Nina Tassler had to say about why they didn't pick up the spin-off.

"There were elements of the pilot that didn't work out. Creative always drives the business. We felt re-piloting was in the best interest. I'm heartsick. It didn't work out."

Greta Gerwig starred in the pilot as Sally, a young New York woman who is on the verge of divorce after being married for a year, finding comfort from her friends and family. Meg Ryan also signed on to narrate the show as the "future Sally." Drew Tarver, Tiya Sircar, Nicholas D'Agosto and Andrew Santino co-star in the pilot, which shares the MacLaren's Pub hangout from How I Met Your Mother.

We'll keep you posted if this spin-off is picked up by another network.
