Whitney Paul returned a fumble 47 yards for one touchdown and Joe Delaney ran 82 yards for another today, leading the Kansas City Chiefs to a mistake-filled 28-14 victory over the Denver Broncos.

The Chiefs, despite fumbling away several scoring opportunities, improved their record to 5-2. They are tied with the Broncos and San Diego Chargers for first place in the AFC West.

Denver quarterback Craig Morton, the NFL's top-rated passer entering the game, completed 25 of 38 passes for 342 yards, including a pair of 11-yard touchdown passes to Steve Watson.

The Chiefs, who had been having trouble putting pressure on quarterbacks, sacked Morton six times.

The Broncos' comeback hopes ended when the 38-year-old veteran had to leave the game late in the fourth period with blurred vision, with his team trailing, 21-14.

"Somebody threw a penny and it hit me in the eye," Morton said. "There was about three minutes left. I was on the sidelines. I just couldn't focus very well."

Billy Jackson's one-yard scoring run and Paul's 47-yard return of a Morton fumble gave the Chiefs a 14-0 lead in the first quarter that held up until Watson's first touchdown in the third period.

Then, just moments after a 70-yard Delaney touchdown run was nullified by a penalty, Bill Kenney threw a swing pass to Henry Marshall, and the veteran Kansas City receiver ran down the sideline for a 64-yard touchdown, giving the Chiefs a 21-7 lead.

Randy Gradishar intercepted a Kenney pass late in the fourth quarter with Kansas City holding a 21-14 edge, and returned it seven yards to the Chief 26. But a penalty and a Don Parrish sack of Morton forced the Broncos to settle for Fred Steinfort's 37-yard field-goal try, which was wide to the right.
