CHICAGO (AP) _ Robert Smith took care of the running this time. Daunte Culpepper did what a quarterback is supposed to do _ throw touchdown passes.

Smith had a 72-yard TD run and became Minnesota's career rushing leader, while Culpepper threw for three scores Sunday night as the Vikings (6-0) stayed unbeaten with a 28-16 victory over the Chicago Bears.

The Vikings struck for two touchdowns in a three-minute span late in the second quarter, overcoming a 9-0 deficit on Smith's 72-yard run and Culpepper's 24-yard scoring pass to Cris Carter.

Smith gained 170 yards on 23 carries and passed Chuck Foreman (5,879) to become the Vikings' career rushing leader. He needed 96 yards entering the game.

Six weeks ago in a 30-27 win over the Bears (1-6) in the season opener, the 6-foot-4, 250-pound Culpepper ran for three touchdowns.

On Sunday night, he used his arm more than his legs, completing 15 of 26 passes for 198 yards. He also threw a 24-yard scoring pass to Matthew Hatchette in the third quarter and a 7-yarder to Randy Moss with just under 10 minutes to play.

Carter grabbed seven passes for 111 yards against the team he's picked on throughout his career. Entering the game, Carter had 132 receptions against the Bears, his most against any NFL team.
