erry Bradshaw, playing despite a sprained shoulder, threw three first-half touchdown passes, two to John Stallworth, as the Pittsburgh Steelers took an early 21-0 lead and went on to defeat the Kansas City Chiefs, 35-14, today.

Stallworth caught scoring passes of 74 and three yards during a four-minute span of the first quarter, then sat out the second half with a pulled stomach muscle. The 74-yarder was the longest touchdown catch of his nine-year career.

"I could have played better," said Bradshaw, who completed 15 of 20 passes for 231 yards in three quarters.

"He threw well and he had time to throw. That was the biggest factor," said Chiefs Coach Marv Levy. "I'm embarrassed we lost the way we did."

The Steelers' defense sacked quarterback Steve Fuller a season-high eight times to help Pittsburgh (4-1) rebound from a 16-0 loss to Seattle last week. In addition, Fuller was intercepted by Donnie Shell in the end zone late in the game.

There were numerous injuries in the game. Pittsburgh's Rick Woods cracked a bone in his left elbow and teammate Fred Bohannon pulled a groin muscle. For the Chiefs (1-4), nose tackle Don Parrish left the game for X-rays of his right thumb and wide receiver J.T. Smith left with a hamstring injury.

The game was a sellout, but there were 1,910 no-shows.
