Sonny Jurgensen has been sacked in NFL-on-CBS' great goldenthroad reshuffle.

A regular CBS-TV analyst the half-dozen seasons since his retirement as a Redskin quarterback, Jurgy bears up under the truth that he no longer is hot network property. He tells The Post's Paul Attner at Carlisle he will bounce right over to the WMAL rdio booth to work the Redskins' games with Frank Herzog and Sam Huff. Any regrets?"No. . . . The switch will help me cover the Redskins better; make me more familiar with them, make my job more comfortable on the weekly TV program ('Redskin Sidelines' on WDVM-TV-9 with Glenn Brenner and guests)". . .

Andy Ockerhausen, WMAL-AM boss, hedges on Jurgensen: "No agreement has been reached, yet." At CBS Sports, Jay Rosenstein of media relations says it's a case of "new management, new perceptions . . . (in commentator pairings) we're looking for chemistry, flexibility, fluidity."

Ah, but wait till next year at CBS-TV and watch the new football commentating jobs open up. The NCAA has decided to go to a two-network plan, 1982-85, on contracts announced yesterday to pick up where the exclusive college football tieup with ABC leaves off after this fall. Where ABC carries 23 games this year, its 16th consecutive as the NCAA football net, ABC and CBS each get 14 "exposures" in '82, an "exposure" being an exclusive time slot in which any number of games can be shown.

Nobody's saying how much wealth is being heaped on the collegiate association for the four-year rights, but the $113 million of ABC's expiring four-year deal with pale by comparison, maybe by 100 percent.

Meantime, for 1981, the sixth annual ABC-NCAA preseason promotion tour begins Sunday at Kings Island, Ohio (College Football of Fame), with a half-dozen stops nationwide in a week's span, and is Maryland's Charlie Wysocki a celebrity or not? The Terp tailback is among six potential all-American accompanying 10 premier coaches on the junket. . .

There, he said it again. His car owner Roger Penske repeated as the hearing resumed Wednesday and driver Bobby Unser reiterated yesterday to the USAC review committee: Unser could have made up the one-lap penalty, for improper passing, that took his Indianapolis 500 victory of May 24 and handed it to Mario Andretti, if only he'd have been told about it on the spot and not after the race was over 50 laps later. . .

Sidney Lowe, the N.C. Stater from De Matha, was credited with a key role in securing the 93-87 victory over the U.S.S.R. that gave the U.S.A. the World University Games gold medal in basketball . . . Dr. Chuck Latourette, the former Cardinal punter, survived a 150-foot plunge in a stalled hang glider and is bedded with broken arms and ribs in the Houston hospital where he now is a staff radiologist . . . Next big event in London? Colts and Falcons are considering a 1982 preseason game there.

A. Dick Bosman (giving pitching clinic Tuesdays and Thursday Aug. 4-Sept. 1 at Fairfax High) is the ex-Senator, Alex and Deron the Johnsons being screened among new (long, longshot) candidates for Cooperstown . . . Q. Last Redskin player inducted into Pro Football Hall of Fame?
