No one has led more late winning drives during the past five seasons than Matt Ryan, and the Atlanta Falcons quarterback did it again Sunday with his fifth one this season.

Ryan guided a six-play, 64-yard drive that ended with Michael Turner's 3-yard touchdown run to put the NFC South leaders ahead for good with 7:55 remaining in a 24-23 victory over the Tampa Bay Buccaneers.

"The last drive, that's something we've done before this season," Falcons tight end Tony Gonzalez said. "I really think that's a positive for us to be able to come up with plays like that when we have to like that. ... I'm really happy with the way we responded."

It's getting to be a way of life. Ryan has put together 21 winning drives in the fourth quarter or overtime since entering the league in 2008 -- four of them against the division rival Buccaneers.

Browns: Team president Mike Holmgren is leaving the organization immediately.

After the Browns' 20-14 victory over the Pittsburgh Steelers, a team spokesman said the game was Holmgren's last with Cleveland. The 64-year-old former coach had hoped to stay until the end of the season in an advisory role but left open the possibility of an earlier departure.

He has been replaced by CEO Joe Banner.

The Browns went 12-31 under Holmgren, hired by former owner Randy Lerner to fix his franchise.

Holmgren has indicated he is still interested in coaching. There have been stories about him joining the Dallas Cowboys.

As a coach, Holmgren won a Super Bowl title in seven seasons with the Green Bay Packers and an AFC championship in 10 seasons with the Seattle Seahawks.

Broncos: Quarterback Peyton Manning led Denver to a 17-9 victory over the Kansas City Chiefs for his 149th career victory, moving into second on the NFL list.

Manning trails only Brett Favre (186) after passing his new boss, John Elway, the Broncos quarterback-turned-executive who acquired Manning in the offseason despite four neck surgeries.

"He's been tremendous," Elway said of Manning. "You know, he's worked hard, and he's come back and proven himself by the year he's having. Plus, he's lifted the whole team. He sets a great example for all of our young guys as far as how hard you have to work to win."

Dolphins: A computer glitch caused stadium lawn sprinklers to douse the Seahawks and the Dolphins during the third quarter. The computer was working on its Saturday schedule, a Dolphins spokesman said.

Seattle quarterback Russell Wilson said the Seahawks were unfazed.

"I think they're used to the rain," he said.

The sprinklers came on between plays and covered most of the field, prompting a brief delay. The sprinklers were quickly turned off, and players toweled off before the action resumed.

"I never saw that before, not even in high school," Miami receiver Davone Bess said. "It was pretty cool."

The Kansas City Star and the Miami Herald contributed to this report.
