Colts quarterback Peyton Manning is worried that an umpire in the backfield could disrupt the team's offense. "It certainly doesn't seem like they took some of the things that we do and other teams do into account when they made the rule," Manning said. "I'm not a big fan of it right now." A new NFL rule has placed an umpire in the backfield heading into this season. He traditionally was stationed on the defensive side of the football, behind the linebackers and 4 or 5 yards off the line of scrimmage. This season, he is on the offensive side, 12 to 15 yards deep, set to the left of the quarterback and opposite the referee.

Colts linebacker Gary Brackett left with a right hand injury late in the first quarter of Thursday night's game against the Packers. He was trying to tackle Ryan Grant on a short gain when it appeared teammate Philip Wheeler came crashing through and hit Brackett's hand on his helmet. Brackett signed a $33 million, five-year deal in the offseason.

Joseph Addai sustained a concussion midway through the third quarter of Thursday night's 59-24 preseason loss to the Green Bay Packers, but he later downplayed the injury. "It's nothing," Addai said after the game. "I was fine. I just got a little dizzy, but I was cool." Addai was hurt while making a tackle of Robert Francois, who scooped up a Peyton Manning fumble after the Colts quarterback was hit as he stepped up in the pocket.

Colts president Bill Polian reports that there has been no progress in negotiations on a long-term contract for quarterback Peyton Manning. "There is no deadline, there is no timeline, [owner] Jim [Irsay] never said there was, I never said there was, [agent] Tom Condon has never said that there was," Polian said. "I talk to Tom all the time, sometimes about Peyton. There have been conversations and there will be." Irsay has said Manning -- entering the final of a seven-year, $98 million contract -- will be the highest-paid player in the league.

Colts center Jeff Saturday will miss two to six weeks of action after having arthroscopic knee surgery. Indianapolis owner Jim Irsay provided the time line after the team failed to do so in a release. "We've seen guys come back in two weeks, you see some guys come back in six weeks," Irsay said. "You're hoping it's the shorter side of the scale."

Colts center Jeff Saturday underwent successful arthroscopic knee surgery to remove a "loose body," the team announced Tuesday. The team didn't reveal how much time Saturday will miss, but he is expected to begin rehabilitation immediately. He has missed just six games since winning the starting job in 2000.

Saints quarterback Drew Brees is keeping an eye on the contract negotiations between Peyton Manning, Tom Brady and their respective teams. Indianapolis owner Jim Irsay has said that he plans to eventually make Manning the NFL's highest-paid player. New England's talks with Brady haven't gone quite as well, but things appear to have turned positive as of late. "Sure. Any guy who plays your position and is in a position where they're negotiating a new contract, that affects you," Brees said. "In a way, I'm paying attention and in a way, I'm not because it's all about playing football right now. It's not the offseason anymore. I know there was talks of that but for now it's just about winning football games and that stuff will take care of itself."

The Colts have signed undrafted offensive lineman James Williams. Williams played his college football at Harvard. Indianapolis released offensive lineman Andy Alleman, an offseason veteran free agent acquisition, to make room for Williams.

Colts defensive lineman John Gill was arrested early Sunday morning after police found him passed out in a ditch on the side of a road. In the police report, Indianapolis officer Ricardo Flores Jr. says he called out to Gill, who tried to stand up, but couldn't and kept falling over. Gill was arrested for public intoxication.

The Colts and first-round pick Jerry Hughes have agreed to terms on a five-year deal. The rookie defensive end missed the team's first training camp practice on Monday while finishing contract negotiations. The Indianapolis Star is reporting that the deal is worth $12 million. Hughes was the 31st overall pick in April's NFL Draft.
