ABC (3:30 p.m. ET)
The Miami Dolphins play the Philadelphia Eagles in the eighth annual kickoff to pro football’s preseason action. An innovation (now that football in July is old hat) is an official NFL test run of TV’s instant replay for second-guessing calls by the refs. At halftime Ray Nitschke, Larry Wilson, Lance Alworth, Tuffy Leemans and Weeb Ewbank will be inducted into the Hall of Fame. Member Frank Gifford will share the broadcast booth with pigskin pontificator Howard Cosell.
