KANSAS CITY, Mo. - Former University of Georgia running back Terrell Davis scored on the longest touchdown run against Kansas City in 19 years, but that couldn't stop the Chiefs from improving to 4-0 for the first time in team history.
Marcus Allen scored on a 2-yard run with 4:09 remaining Sunday to give the Chiefs a 17-14 victory over Denver in a battle of unbeaten AFC West rivals.
Like practically every score by Allen his season, his 106th rushing TD was a milestone, tying Jim Brown for second on the career list, four behind Walter Payton.
Dale Carter's lunging interception of John Elway's long pass sealed Kansas City's 12th straight AFC West victory and kept them unbeaten in regular-season home games since Denver beat them in overtime on Dec. 4, 1994.
The Chiefs overcame fine performances by Davis and Shannon Sharpe. Davis rushed for 141 yards, and Sharpe had 131 yards receiving.
Davis, a second-year running back, broke a 65-yard TD run for a 14-10 lead in the second quarter. It was the longest scoring run against Kansas City since Houston's Ron Carpenter went 77 yards in 1977.
Davis, who entered the game as the AFC's leading rusher with 320 yards, burst through a hole on the right side and outran Mark Collins and Carter, the Chiefs' fastest defender.
As Carter slowly closed the gap, Davis veered left, then veered left again, keeping just ahead him until the cornerback dragged him down in the end zone. On the previous play, Elway had scrambled 15 yards on third-and-11.
The Chiefs hadn't given up a 100-yard rushing day at home since Seattle's Chris Warren got 117 on Oct. 23, 1994.
Chiefs quarterback Steve Bono, who had been booed the previous series, brought cheers from the capacity crowd of 79,439 in the winning 67-yard drive when he hit Danan Hughes for 16 yards and Chris Penn for 18 on successive plays.
The Broncos (3-1) took the opening kickoff and burned 7:34 off the clock on a 14-play, 74-yard drive that Davis capped with a 6-yard run. Elway passed for 53 yards and converted four third downs in the march, including a third-and-10 when he hit Sharpe for 19 yards to the 31.
After Pete Stoyanovich's 37-yard field goal made it 7-3 with 57 seconds left in the first quarter, fullback Kimble Anders got loose for a 45-yard pass reception - his longest as a Chief - to key a 75-yard TD drive that gave Kansas City the lead. Anders, who went to the Pro Bowl for the first time last season, hauled in the pass on the left sideline, broke Bill Romanowski's tackle and made it all the way to the 37.
Bono hit former Bronco Reggie Johnson for 15 yards on the next play, then capped the march with an 8-yard flip to a leaping Danan Hughes in the end zone. After Jason Elam missed a 52-yard field goal attempt in the second quarter, the Chiefs appeared to be driving toward another score when Bono, on first down from the Denver 28, threw his first interception in 93 pass attempts this season. Romanowski picked off the ball on the 21, and three plays later Davis was in the end zone after his 65-yard gallop.
Two of the worst passes Elway has thrown all year preceded Stoyanovich's 37-yarder in the first quarter. Given plenty of time on second-and-15 from the Denver 35, the ball popped out of Elway's hand and went straight up in the air as his arm moved forward. On the next play, he threw a wobbly pass to safety Mark Collins, who was standing by himself in the middle of the field and returned the ball 23 yards.
