The Cougar Town star will play Fred - an intelligent film editor - in the CBS multi-camera project about a group of poor young people looking to achieve their dreams, reports Deadline.
The untitled comedy, written by Louis CK and to be directed by Andy Ackerman, is in second position behind Cougar Town for Byrd, which means the role of Fred will be recast if Cougar Town is picked up for another season.
Cougar Town co-star Josh Hopkins has also signed up for a pilot in second position. He is attached to NBC's Lady Friends.
Byrd previously appeared in the Emma Stone comedy Easy A and had a guest spot in sitcom Suburgatory.
He also played Luke Campbell for three episodes of Heroes in 2009.
