George Rogers ran for 206 yards, including 76 yards for a touchdown in the third quarter, to lead the New Orleans Saints to a 28-17 victory over the St. Louis Cardinals today.

New Orleans trailed, 10-7, when Rogers ran through a pair of hands at his 24-yard line, bowled over safety Benny Perrin at the 35, then outraced everyone the remaining 65 yards.

Saints offensive tackle Dave Lafary says the Cardinals knew what was coming on Rogers' run. "They were saying 'Draw, draw, draw.' They knew it was coming . . . ," Lafary said.

Rogers scored later on a one-yard plunge after a bizarre interception of Jim Hart. Passing from his own 18, Hart's toss was tipped by cornerback Rodney Lewis, then caught by linebacker Dennis Winston. Teammate Frank Wattelet knocked the ball from Winston's hands at the St. Louis five, and Lewis recovered it there.

Hart relieved Neil Lomax at the half after Lomax suffered a sprained right shoulder; he is doubtful for Sunday's game against Dallas. Saints quarterback Kenny Stabler bruised a knee on his first passing attempt--the Saints' third play--when he was hit by tackle Elois Grooms as he threw. Stabler will be examined Monday. Dave Wilson replaced Stabler.
