CBS and NBC each announced mid-season changes on Monday, and in the case of CBS, The Changes were minuscule. The new Rob Schneider comedy Rob!, about a middle-aged bachelor who marries a Hispanic woman, will debut Jan. 12, replacing Rules of Engagement, and a third season of Under cover Boss will debut on Jan. 15, replacing The Amazing Race . NBC, on the other hand, is completely rejiggering its schedule, with The Cult favorite Community being bounced, at least temporarily. Also off the NBC schedule for the time being is Prime Suspect . Neither show has been canceled outright. Joining the NBC lineup are two comedies -- Fashion Star and Are You There, Chelsea? -- and two dramas -- The Firm and Smash.
