1971: Gordie Howe announces his retirement after 25 seasons with the Detroit Red Wings and is named a team vice president.

The 43-year-old right wing owns the NHL career marks for games played, goals, assists and points, but he's coming off his worst offensive season (23 goals, 52 points) since 1948-49 when he decides to retire. The Hockey Hall of Fame waives its mandatory three-year waiting period, and he's inducted in 1972.

But after two seasons off the ice, Howe returns as a player with the Houston Aeros of the World Hockey Association, skating with his sons Mark and Marty. Howe spends six seasons in the WHA, the last two with the New England Whalers, before the franchise, now known as the Hartford Whalers, joins the NHL in 1979. He plays all 80 games in 1979-80, finishing with 41 points (15 goals, 26 assists), before retiring for good shortly after his 52nd birthday.

1972: The Soviet Union defeats Canada 5-3 in Game 4 of the Summit Series at Pacific Coliseum in Vancouver.

Boris Mikhailov scores two first-period power-play goals for the Soviets, who win easily despite being outshot 41-31. Canada trails 4-1 after two periods and the final score looks closer than the game was after Dennis Hull scores for Canada with 32 seconds remaining in the third period.

Phil Esposito, one of Canada's leaders, is unhappy when fans boo the team off the ice following the game.

"To the people across Canada, we tried. We gave it our best," he says during a postgame TV interview. "To the people who booed us, geez, all of us guys are really disheartened. We're disillusioned and disappointed. We cannot believe the bad press we've got, the booing we've got in our own building.

"I'm completely disappointed. I cannot believe it. Every one of us guys -- 35 guys -- we came out because we love our country. Not for any other reason. … We came because we love Canada."

The Soviets lead the series 2-1 with one tie entering the two-week break before Games 5-8 are played in Moscow.

Ullman, whose career is divided between the Red Wings and Toronto Maple Leafs, is the fifth player in League history to reach 1,000 points and finishes his 20-year NHL career with 1,229 points (490 goals, 739 assists) in 1,410 games.
