American Football: Crunch Match....Kansas City Chiefs and Denver Broncos

The Kansas City Chiefs and Denver Broncos collide on Sunday in the first clash of teams seeking their fifth straight wins in the 32-year history of Arrowhead Stadium.

The Chiefs will be seeking their first-ever 5-0 start - the Broncos, however, reached 13-0 in 1998 under coach Mike Shanahan.

The AFC West rivals have played overtime contests here each of the last two years.

The Broncos won 37-34 last October, but have not won in consecutive years at Arrowhead since 1976-79.

Keith Burns blocked a punt in overtime and a pass interference penalty on Chiefs cornerback Eric Warfield helped set up the winning 25-yard field goal by Jason Elam.

It was a memorable day for future Hall of Famer Shannon Sharpe, who set an NFL single-game record for receiving yards by a tight end with 12 catches for 214 yards and two touchdowns.

In the rematch at Denver on December 15, Clinton Portis rushed for 130 yards and scored three touchdowns, including a 66-yard reception, in a 31-24 victory for the Broncos.

Portis missed last week's 20-16 win over Detroit with a bruised sternum and is i9n doubt for Sunday.

Sunday's game will match up two of the NFL's highest scoring offenses. The Chiefs, averaging 31.8 points per game, are set to score 508 points, which would surpass the franchise record of 467 last season.

well they won..
