Former Washington Redskins safety Ken Houston is among seven finalists for the Pro Football Hall of Fame.

The last vote in the Hall of Fame process was taken by 28 selectors this morning. Results will be announced Tuesday. At least four men will be inducted and any others with 23 votes also qualify.

The finalists: Houston, quarterbacks Fran Tarkenton and Len Dawson, halfback Paul Hornung, linebacker Willie Lanier, wide receiver Don Maynard and halfback Doak Walker, nominated by an old-timers committee.

In 14 seasons, the first six with the Houston Oilers, Houston set NFL records for most career touchdowns on interceptions (nine), most season touchdowns on interceptions (four) and most touchdowns on interceptions in one game (two). He started nine postseason all-star games.

Of those who failed to make the final cut, from 10 to six, this morning, former Dolphins and Giants running back Larry Csonka and Raiders managing partner Al Davis were the most surprising.

Csonka is regarded as the essence of a ground-oriented Miami team that compiled the only 17-0 season ever in the NFL and won back-to-back Super Bowls.

Davis was nominated as a contributor, for being a coach, a general manager and an owner. In addition, as commissioner of the American Football League, he was prominent in forcing the merger with the NFL.

Hornung's not being selected has been controversial. Several other prominent players from Vince Lombardi's Packers are enshrined; many argue that Hornung was the best, but still tainted by being banned from football for the 1963 season by Commissioner Pete Rozelle for gambling.

Tarkenton also seems overdue for election, since he set numerous passing records and led the Vikings to three Super Bowls.

Lanier was the core of a Kansas City defense that upset the Vikings in Super Bowl IV. He made seven straight all-pro teams. Teammate Dawson was the quarterback of that Kansas City Super Bowl team.

Maynard was the long-ball threat on the Joe Namath-led Jets. He is first in career reception yards (11,834) and third in career receptions (633).
