Jackson's role on ABC's college football coverage occasionally interfered with his postseason baseball commitments. For instance, he was unavailable to call Game 1 of the 1976 ALCS because he had just finished calling an Oklahoma-Texas college football game for ABC. Thus, Bob Uecker filled-in for Jackson for Game 1. In 1978, Jackson called another Oklahoma-Texas football game for ABC on the afternoon October 7, then flew to New York, arriving just in time to call Game 4 of the 1978 American League Championship Series that same night. On October 11, 1980, Jackson once again called an Oklahoma-Texas football game for ABC in the afternoon, then flew to Houston to call Game 4 of the 1980 National League Championship Series. In the meantime, Drysdale filled-in for Jackson on play-by-play for the early innings.
