retired during the 1989 off-season. He joined the NFL in 1968 as a line judge before being promoted to referee in 1969. Games that he officiated include Super Bowl XIV and the Freezer Bowl. Dale Hamer, the head linesman for Super Bowl XVII and Super Bowl XXII, and Howard Roe were promoted to referee.

Major rule changes
After a foul that occurs inside the last two minutes of the first half and inside the last five minutes of the second half or overtime, the game clock will start at the snap, instead of when the ball is spotted and the Referee signals it is ready to be played.
New rules were enacted, including loss of timeouts or five-yard penalties, to handle the problem of crowd noise when it becomes too loud for the offensive team to hear its signals.
If a receiver and a defender eventually establish joint control of a pass, the ball will be awarded to whoever was the first player to establish control of the ball.
While not a rule “change” per se, the “hurry up offense” was recognized as fully legal, and penalties for delay of game would be called against teams whose defenders faked injuries in order to slow down the tempo, unless those teams called for timeouts.
