Following Fox ordering a full season of Rob Lowe’s “The Grinder,” the network has given the same treatment to the John Stamos sitcom “Grandfathered,” Variety has learned.

The Tuesday night comedy has fared well in its early run, and chances of landing a full season were high, as Fox ordered six additional scripts of “Grandfathered” earlier this month.

In its four weeks on the air, “Grandfathered” was averaging a 1.6 rating in adults 18-49 and 5.1 million viewers overall in Nielsen’s “live plus-3” estimates. It grew in rating with its most recent episode.

“’Grandfathered’ had the Herculean task of self-starting on what is an incredibly competitive Tuesday night, and the series has proven itself up to the challenge,” said David Madden, president of entertainment at Fox Broadcasting Company. “Since the very beginning we knew this show would be that rare commodity — a genuinely original family comedy. The remarkable John Stamos, Josh Peck, Paget Brewster, and the entire cast have sparkling chemistry, and the show’s creative team has delivered fantastic scripts that keep these great characters moving.  We know fans are going to love the surprises in store for the rest of the season.”

Created by Danny Chun, the half-hour laffer follows Stamos’ character, a longtime bachelor who suddenly finds out that he’s a father — and a grandfather.

“Grandfathered” is part of Fox’s all-new Tuesday night block this fall, airing before “The Grinder” and “Scream Queens.” The three series are currently on a brief hiatus during the net’s coverage of the World Series.

In addition to “Grandfathered” and “Grinder,” ABC’s freshman comedy “Dr. Ken” starring Ken Jeong, was the season’s first new comedy to get a full-season order. Yesterday, CBS gave a full season to ensemble family comedy “Life in Pieces.” However, NBC’s new sitcom “Truth Be Told” was recently trimmed to 10 episodes after an early lackluster performance had it ranking as the lowest-rated of any series on the Big Four networks this fall.
