During the 1990 season, Pat Summerall was hospitalized after vomiting on a plane during a flight after a Bears–Redskins game, and was out for a considerable amount of time. While Verne Lundquist replaced Summerall on games with Madden, Jack Buck (who was at CBS during the time as the network's lead Major League Baseball announcer) was added as a regular NFL broadcaster to fill-in.
