CHARLOTTE, N.C. -- Peyton Manning set another record and the Indianapolis Colts are 7-0 again.
Manning shook off a slow start to throw for 254 yards and two touchdowns and broke Johnny Unitas' team record for career scoring passes in the Colts' 31-7 win over the injury-plagued Carolina Panthers on Sunday.
Joseph Addai rushed for 100 yards and two touchdowns and caught a TD pass from Manning, who was outplayed early by 43-year-old Vinny Testaverde.
But when Testaverde left at halftime with tendinitis in his right Achilles tendon, Manning made sure the Colts' much-anticipated matchup with Tom Brady and the Patriots this Sunday wouldn't be tarnished by dominating the second half.
Never miss a local story.
The Colts became the first team since the 1929-31 Green Bay Packers to win their first seven games for three consecutive seasons.
It took Manning nearly the entire first quarter to get on the field. He didn't complete a pass until early in the second quarter and started 2-for-9.
"When we've had halves like that in the past, there would be a little frustration," said coach Tony Dungy, who passed Don Shula for the most wins in Colts' history with 74. "But we've been there, and our guys do have a lot of confidence in our coaching staff."
The Panthers (4-3) took a 7-0 lead behind Testaverde, who turns 44 in two weeks.
Getting the starting nod for the second consecutive game ahead of David Carr, who's still recovering from a back injury, Testaverde led the Panthers on an opening 80-yard touchdown drive. It lasted a team record-tying 18 plays and more than 11 minutes, the longest by time in the NFL this season.
But Testaverde also was intercepted by Antoine Bethea in the end zone in the second quarter, and aggravated an existing Achilles tendon injury when guard Mike Wahle stepped on his foot.
After completing 12 of 20 passes for 82 yards, Testaverde began the second half with an ice pack around his ankle and sitting on the bench next to Jake Delhomme. Carolina's original starting quarterback was in a sling after undergoing season-ending elbow surgery.
Before Carr could replace him, the Colts had taken a 17-7 lead on Manning's 4-yard touchdown pass to Addai on the first drive of the second half.
Manning completed just 14 of 30 passes, but shook off early problems to eclipse another one of Unitas' records. His second touchdown, a perfectly thrown 59-yard pass to Reggie Wayne late in the third quarter, was the 288th of his career, one more than Unitas.
Held without a catch after the opening drive, Carolina receiver Steve Smith was seen screaming at Carr on the sidelines late in the game.
"I'm trying to get him the football. And he's not necessarily concerned about himself getting the football," Carr said of Smith.
"He just wants our team to be better. I just went up to him and said, 'If there's anything I can do that you see from the wide receiver position that can make us a better team, then let me know.'
"We just got talking because we're too old to keep secrets from each other. And he's not like that at all. He'll tell you straight up."
