There are no more unbeaten teams in the NFL. There are two teams with a tie, though.
New Orleans knocked off the last of the perfect teams when it beat archrival Atlanta 31-27 Sunday.
Jimmy Graham caught seven passes for a career-best 146 yards and two touchdowns, outdueling Tony Gonzalez as tight ends took the spotlight in the Big Easy.
Gonzalez finished with 11 catches for 122 yards and two scores for Atlanta (8-1), and became the first tight end to catch 100 touchdown passes.
"Tony, he kind of paved the way for me," said Graham, who like Gonzalez had a college basketball background before making the transition to NFL tight end. "It seemed like every drive I'm kind of going up against the things that he did the last drive."
Jabari Greer made a diving, touchdown-saving pass breakup on a late fourth-down play as the Saints (4-5) won for the fourth time in five games, keeping alive hope of getting back into the wild-card race after an 0-4 start.
Games can't get much wilder than San Francisco's 24-24 tie with St. Louis, the league's first stalemate in four seasons.
Greg Zuerlein kicked a 53-yard field goal in OT to win it -- except the Rams (3-5-1) were penalized 5 yards for delay of game. He tried again from 58 as coach Jeff Fisher played for the win, and missed wide right with 2:42 left.
San Francisco's David Akers missed wide left on a 41-yard attempt that could have sealed it for the 49ers (6-2-1), who lost quarterback Alex Smith to a first-half concussion.
And just when it seemed the 49ers -- and Akers' typically reliable left leg -- would have one more chance to win it, San Francisco linebacker Patrick Willis was flagged for holding Lance Kendricks on third down. That extended St. Louis' last drive, a costly mistake in a long list of them on an uncharacteristically sloppy day by coach Jim Harbaugh's team.
Akers made a tying 33-yarder with 3 seconds left in regulation after Sam Bradford threw a 2-yard touchdown pass to Austin Pettis with 1:09 remaining.
"I have to say, I've been doing this a while. I don't think I've ever been in a game like this," Fisher said. "As I told our guys, we had a number of chances to put the game away. And, unfortunately, we didn't."
Also Sunday, it was Houston 13, Chicago 3; Baltimore 55, Oakland 20; Denver 36, Carolina 14; Tennessee 37, Miami 3; New England 37, Buffalo 31; Cincinnati 31, the New York Giants 13; Dallas 38, Philadelphia 23; Tampa Bay 34, San Diego 24; Minnesota 34, Detroit 24; and Seattle 28, the New York Jets 7.
On Thursday night, Indianapolis (6-3) beat Jacksonville (1-8) 27-10.
The Monday night game has Kansas City (1-7) at Pittsburgh (5-3).
Idle this week were Green Bay (6-3), Washington (3-6), Arizona (4-5) and Cleveland (2-7).
SAINTS 31, FALCONS 27
At New Orleans, Drew Brees threw for 298 yards and three TDs for the Saints, who made a late goal-line stand to preserve the win. Brees is 11-2 against Atlanta since joining New Orleans in 2006.
"No one is going to go around crying or panicking or anything like that," Gonzalez said. "We're a good team. Our confidence hasn't changed."
49ERS 24, RAMS 24
At San Francisco, on the first play of OT, Bradford completed an 80-yard pass to Danny Amendola that took St. Louis to the 2, but the play was called back for an illegal formation.
The previous NFL tie was between Philadelphia and Cincinnati, 13-13 in 2008. San Francisco played its first tie since 1986.
"It just feels like it's unfinished business," San Francisco cornerback Tarell Brown said.
"I think anyone would like to keep playing. I really don't know what good a tie does," Bradford said. "It's frustrating when you play a game and you put so much into it during the week and during the course of it, today five quarters, you'd like to come away with either a win or a loss."
TEXANS 13, BEARS 6
At Chicago, the Texans improved the AFC's best record to 8-1, equaling Atlanta's mark in the NFC, as well, by beating another league power.
Arian Foster finished with 102 yards rushing and a touchdown catch, and the Texans intercepted Jay Cutler twice before knocking him out of the game with a concussion.
Foster was the only reliable offensive weapon on either side, particularly in the first half when he ran for 85 yards and made a sprawling catch for a 2-yard touchdown to put Houston ahead 10-3.
