As NBC gets ready to kick off  Broadcast Upfront Week Monday morning at Radio City Music Hall, the network has decided to cancel what was once considered one of its most promising series for this season, the Matthew Perry ensemble comedy “Go On.”

“Go On,” in which “Friends” alum Perry played a sportscaster getting over the death of his wife, was one of an elite group of new NBC shows the network launched during its highly-watched London Summer Olympics. In its sneak preview, it averaged nearly 19 million viewers , after which it was given a cushy timeslot following NBC’s hit singing competition, “The Voice,” on the net’s fall schedule. But when “The Voice” took a breather in the first quarter, “Go On’s” ratings faltered.

Meanwhile, the network has ordered a new Bill Lawrence comedy about a slacker who takes in socially awkward friends, an exhumation of NBC’s 70’s cop drama “Ironside,” and a Chicago-set Dick Wolf cop drama.

“Undateable,” from Bill Lawrence — who made a name for himself complaining about the way NBC treated his comedy series “Scrubs” — is about a confident slacker named Danny (played by “Whitney” star Chris D’Elia, now that NBC has officially nuked “Whitney”) who takes in a roommate, named Justin, and inherits Justin’s entourage of undateable friends. Danny decides to teach these Undateables, the “do’s, don’ts and duhs of dating,” NBC confirmed Friday.

“Undateable” joins a crop of new comedies at NBC that will also inclue one about a blind guy who gets a guide dog because his wife divorced him,  called “The Family Guide”; “Sean Saves the World,” starring Sean Hayes as a divorced gay dad whose daughter moves in full time; and a TV re-make of the 2002 Hugh Grant flick “About a Boy.”

On the drama front, NBC made official its pickup of “Ironside,” a remake of the network’s ‘70’s drama of same name, with Blair Underwood cast in the role of paralyzed, wheelchair-bound NYPD Det. Robert Ironside (played by Raymond Burr in the original). 

And “Chicago PD” will allow Dick Wolf to amortize those Chicago exteriors across two programs — he’s already got “Chicago Fire” on NBC’s lineup. “CPD” is about the two, distinctly different groups in the Chicago PD: the uniformed cops who patrol the beat and the Intelligence Unit that combats the city’s organized crime, drug trafficking and high-profile murders.

“Ironside”  and “Chicago PD” join the already ordered new NBC dramas “Crisis,” about the kidnap of Washington, D.C.’s blue-blooded kids during a field trip; and “Believe,” about a girl with special powers who is being guarded by a guy sprung from death row.
