Brackett returned a fumble 68 yards for a touchdown with 3:36 remaining in the game to pull the Colts within three points, 27-24.
Down 27-10 midway through the fourth quarter, the Colts became the first NFL team to erase a 17-point deficit in a game's final five minutes to win in regulation.
Brackett's touchdown came between two Peyton Manning touchdown passes, the first to Tom Santi with 4:04 remaining and the game-winning touchdown to Reggie Wayne with 1:54 left. Brackett also had six tackles.
Brackett earned a defensive game ball for his performance, and his fumble return was the basis of some good-natured teasing from some of his teammates.
"They were asking me how fast I was running (on the fumble return)," he joked. "I told them fast enough."
It marks Brackett's second career Player of the Week honor. He also was named following the Colts Week 1 win at Baltimore in 2005, when he had nine tackles and two interceptions.
QB Peyton Manning
With his 32nd career game-winning drive accomplished against Houston on Sunday, Manning slipped past John Unitas to take the franchise record in that category.
Manning had a 101.0 efficiency rating against the Texans. He has achieved a 100-plus rating 62 times. The Colts are 54-8 in those games.
RB Joseph Addai
Addai ran for 71 yards on 17 carries in the Houston game. Addai, though, has not reached the 100-yard rushing mark in a game since Nov. 4, 2007, when he had 112 yards against New England. That's a streak of 14 straight games, including the playoffs, in which he has not dented the 100-yard mark.
Harrison ran his career reception total to 1,059 and passed Jerry Rice (1,057) for the most in the first 13 years of a career. Harrison hauled in four passes for 32 yards against the Texans on Sunday.
The prognosis for Gonzalez looks to be good. Gonzalez left the Houston game in the second half Sunday after receiving a blow to the head. The injury was initially reported to be a concussion, although there isn't expected to be an update on the injury until Wednesday at the earliest. Coach Tony Dungy said Gonzalez told him Monday that he thought he would be all right.
TE Jacob Tamme
Tamme has not played since the season opener against Chicago. Tamme has been bothered by an ankle injury that has forced the Colts to keep him on the sideline.
Tamme, though, got some practice time in last week and could see more work heading into the Baltimore game.
DT Raheem Brock
On closer review, it appears as if DE Dwight Freeney may have been involved on the hit as well. But Brock doesn't seem to mind sharing the credit. "We were trying to get to the quarterback and make him make some mistakes," Brock said.
Jackson made the first hit on a leaping QB Sage Rosenfels on the momentum-changing play Sunday. Jackson was a bit nicked up earlier the game but was able to fight through it. He appeared to have hurt his lower right leg or foot. He is expected to be available for this week's home game with Baltimore.
Hayden is keeping his fingers crossed that the left knee injury he suffered Sunday against Houston won't keep him out of any future games. "I took a MRI (Monday) morning and the doctors didn't get back to me yet, so I'm just sitting back waiting," he said.
S Jamie Silva
Silva got a special teams game ball for his overall performance against the Texans on Sunday. Silva, an undrafted free agent from Boston College, has played in the last two games for the Colts after being signed off of the team's practice squad.
