Cleveland ? In a matter of seconds, Dwayne Rudd lost his head, his helmet and the game.

Rudd drew an unsportsmanlike conduct penalty for throwing his helmet in celebration, setting up Morten Andersen’s 30-yard field goal with no time showing Sunday and giving the Kansas City Chiefs a stunning 40-39 win over the Cleveland Browns.

Kansas City kicker Morten Andersen (8) is mobbed by teammates after his game-winning field goal. Andersen connected from 30 yards with no time showing on the clock as the Chiefs rallied to beat Cleveland, 40-39, Sunday in Cleveland.

“I’m sick,” Browns coach Butch Davis said. “To have something like that happen at the end is inexcusable.”

And unbelievable for the Browns, who had their second straight bizarre finish at home. Cleveland’s home finale last season ended with angry fans throwing thousands of plastic beer bottles on the field to protest a call overturned by instant replay.

Bottles are now banned in Browns Stadium. Rudd’s lone projectile cost Cleveland this time.

“I shouldn’t have taken it off,” Rudd said. “It’s against the rules. I thought we had won.”

Rudd, thinking he had sacked Kansas City’s Trent Green, had his back to the play and didn’t see the quarterback flip the ball to 6-foot-6, 323-pound tackle John Tait, who rumbled 28 yards to the Browns 25.

As Rudd retrieved his helmet which he tossed 15 yards down field the officials moved the ball half the distance to the goal line for Andersen, whose game-winning kick capped a 23-point fourth quarter for Kansas City.

“This was just luck,” said Chiefs tight end Tony Gonzalez, who missed training camp but had five catches for 87 yards and a TD. “The coaches might call it preparation or whatever. But to me, it’s luck, and I’ll take it every time.”

Priest Holmes matched a club record with four TD runs three in the final 9:06 and had 122 yards for the Chiefs, who trailed 30-17 with 11:19 left after Cleveland’s Phil Dawson kicked a 34-yard field goal.

“Right then, we’ve got to shut the door,” Davis said.

Kelly Holcomb, who started at quarterback for the injured Tim Couch, was 27-of-39 for 326 yards and three TD passes for the Browns.

Dawson had four field goals for Cleveland, which lost three games on the final play two in OT in 2001.

Dawson’s fourth field goal with 29 seconds left extended his streak to 19 in a row dating to last season and put the Browns ahead 39-37.

However, Cleveland holder Chris Gardocki was called for taunting on the kick, forcing Dawson to kick off from his own 15 and the Chiefs returned it to the 35. TV replays appeared to show that it was Dawson who had yelled at one of the Chiefs.

On first down, Green ran for 12 yards and quickly lined up the offense before spiking the ball with four seconds left.

The Chiefs sent all their receivers deep into the right end zone to try a final, “Hail Mary” play. Green was flushed from the pocket and was about to be sacked by Rudd when he alertly tossed the ball behind him to Tait.

“I was just looking for a red jersey, and I saw it was John,” Green said. “We’re going to have to check his background to see if he was a running back at any point in his career.”

With a couple blockers in front of him, Tait then stomped his way down the left sideline in front of Cleveland’s shocked bench before being run out of bounds by safety Devin Bush.

Tait said he knew Green was in trouble.

“We made eye contact and he flipped me the ball,” Tait said. “I’ve never had the ball before, not even in Pop Warner. When I was a kid I always dreamed about doing something like that, but in the dream, I score the winning touchdown.”

Rudd was sure he had tackled Green before the quarterback got rid of the ball.

“I thought he was down,” Rudd said. “When I tackled him, he rolled over on my facemask. I looked up and saw triple zeros on the clock and thought the game was over.”

The Browns thought they had won their season opener and began walking across the field to shake hands when referee Ron Blum waved them back to the bench.

Blum then announced the infraction against Rudd, and said Kansas City’s kick would be an untimed play.

Andersen, who kicked a 33-yarder in the third quarter, then split the uprights to give Kansas City the stunning victory and cap a wild afternoon of scoring.

“I went to BYU, man,” Tait said. “I’m used to these high-scoring games but it’s never over ’til it’s over.”
