Manning threw four touchdown passes against the New England Patriots Sunday, but it was three interceptions that he threw that bothered him afterward.
Manning, who completed 38 of 52 passes for 396 yards, threw two fourth-quarter touchdown passes and drove the Colts to the Patriots' 24 before James Sanders' interception secured a 31-28 victory for the Patriots at Gillette Stadium in Foxboro, Mass.
"Certainly we had a chance, but I put our team in the hole," Manning said. "I made it tough all night."
The final interception came on 1st-and-10 from the 24, and came as Manning threw to his right toward wide receiver Pierre Garcon.
Manning was under pressure as he threw and called the play a "bad throw."
"I certainly didn't get everything on the throw that I wanted," Manning said. "We had the matchup that I wanted and I took a shot at the end zone and I just did not -- I can't tell the reason -- I just did not get everything I wanted on the throw."
Asked specifically about the last throw, Manning said, "If you're asking if I'm stewing about it right now, the answer would be yes."
The Colts had trailed 31-14 in the fourth quarter -- the same score by which they trailed the Patriots a year ago before rallying for a 35-34 victory.
"I'm just sick about not extending the game," Manning said. "There's just no excuse just not to extend the game there and give (Adam) Vinatieri a chance for a field goal. Certainly, we were going for the win. We had some time, had some timeouts and felt like we had a good play call. Just a poor throw and it's really sickening. ...
"We did a good job until the end; had a chance to win it and (it's) just sickening that we didn't have a chance to extend the game."
