Peyton Manning still thinks he can be ready for the Indianapolis Colts' regular-season opener.
The rest of the preseason appears to be out.
Manning said Saturday he will use the next two weeks to get healthy from offseason neck surgery, a timeline that could put his streak of 227 consecutive starts in jeopardy.
"I certainly want to be out there, and it's hard to keep track of the hours I've spent in rehab," he said. "I was short-changed a little bit by the lockout and I'm going to need every bit of the next two weeks, and then I can give you more of an update with where I am."
The only four-time MVP in NFL history spoke at halftime of Saturday's second high school football game at Lucas Oil Stadium. The annual tripleheader is hosted by the PeyBack Foundation, Manning's charity.
He underwent neck surgery in May to repair a nerve and has been on the Colts' physically unable to perform list since the start of camp.
While Colts coach Jim Caldwell hasn't said when Manning might return to the practice field, it's clear there are concerns within the team.
About 6 hours before Manning spoke, team owner Jim Irsay used his Twitter account to acknowledge there's a possibility the Colts will start the season without their No. 1 QB.
Manning said he was unaware of Irsay's comments because he had been busy rehabbing. He signed a five-year, $90 million contract in July after the 4 1/2 -month lockout ended.
The notion of not having Manning line up behind center will undoubtedly make Colts fans cringe and, until now, seemed inconceivable.
Since being the No. 1 overall pick in the 1998 draft, Manning has started all 208 regular-season games and 19 more in the playoffs, the second-longest streak for a quarterback in league history behind only Brett Favre's 297.
But the recovery from the second operation on his neck in 15 months, has been slower than expected.
"I have made progress, but I still have some work to do," he said. "When I'm healthy enough, I'll be able to play."
The only other time one of his starts appeared to be in jeopardy was in 2008 when Manning needed two operations to remove an infected bursa sac from his left knee. He missed all of training camp and the entire preseason, then struggled early in the regular season before winning his third MVP award.
Backup quarterback Curtis Painter has started both preseason games and has completed 8 of 16 passes for 95 yards with no touchdowns and one interception. In Friday night's 16-3 loss to Washington, Painter managed only one first down and couldn't get the offense past its 29-yard line despite playing the entire first half.
His career numbers are 8 of 28 for 83 yards with no touchdowns, two interceptions and a quarterback rating of 9.8.
