PRO FOOTBALL—Pittsburgh, Los Angeles and Washington remained undefeated, but the Steelers and Rams had to struggle to maintain their perfect records. In Pittsburgh, Terry Bradshaw's 100th career touchdown pass, a 37-yarder on a flea-flicker to Tight End Bennie Cunningham, gave the Steelers a 15-9 sudden-death victory over previously unbeaten Cleveland (page 22). The Rams had to overcome a series of second-half mistakes to defeat Houston in the Astrodome 10-6. Cullen Bryant scored on a three-yard run and Frank Corral kicked a 25-yard field goal as Los Angeles scored all its points in the first half. NFC Eastern leader Washington had no trouble with the New York Jets, coasting to a 23-3 victory in Washington. Quarterback Joe Theismann, in perhaps his finest performance as a Redskin, completed 21 of 30 passes for 209 yards, two for touchdowns—a 33-yarder to John McDaniel and a 20-yarder to Jean Fugett. The Redskins' defense sacked Jet Quarterback Richard Todd four times, forcing him from the game in the fourth period with a dislocated left clavicle. He will be sidelined from six to eight weeks. With Wilbert Montgomery rushing for 111 yards in 25 carries, Philadelphia beat Miami 17-3, dropping the Dolphins into a first-place tie with the Jets and New England. Joe Ferguson passed 19 yards to Reuben Gant and 28 yards to Frank Lewis to lead Buffalo to its first victory, 24-17 over Baltimore. The key score for Buffalo came on Curtis Brown's 102-yard kickoff return, the longest of the season. Denver took a one-game lead over Oakland in the AFC West. The Broncos defeated the Chiefs 23-17, when rookie Dave Preston plunged in from one yard with 4:32 remaining in sudden death. Denver's Jim Turner kicked his 282nd career field goal, tying him with former Minnesota Viking Fred Cox for second place on the alltime list. In Oakland, the Raiders dropped a 21-14 decision to New England when Sam Cunningham scored from one yard out with 16 seconds left. Cincinnati lost its fourth straight, to New Orleans, 20-18. John Leypoldt—signed last week when the Saints' regular kicker, Rich Szaro, was injured—kicked a 27-yard field goal as time ran out, and the Saints evened their record at 2-2. Green Bay won its third game in four tries, beating the Chargers 24-3 as well as the 102� heat in San Diego Stadium. Walter Landers ran 15 yards with a blocked punt for one Packer touchdown and Cornerback Willie Buchanon, tying an NFL record, intercepted four passes, and ran one back 77 yards for a score. The next day, San Diego Coach Tommy Prothro resigned and was replaced by Don Coryell. Jim Zorn threw three fourth-quarter touchdown passes, including a four-yarder to Ron Howard for the go-ahead score with 9:17 left, to give Seattle a 28-16 victory over Detroit, the Seahawks' second straight win. Robert New-house scored two fourth-quarter touchdowns to lead Dallas to a 21-12 defeat over winless St. Louis.
