The Hollywood Reporter said the network planned to run out the clock with the remaining seven episodes airing Saturday night after "Two and a Half Men" reruns.
"Gentleman" stars David Hornsby, Kevin Dillon and Mary Lynn Rajskub and centers on the relationship between a newspaper columnist and his personal trainer.
The show premiered Sept. 29 after "The Big Bang Theory" but fared poorly in the 18-49 year demographic when compared to its 2010 predecessor "$#*! My Dad Says," the Reporter said. The numbers never recovered and "Rules of Engagement" will be moved into the Thursday time slot.
