Orton will start at QB for Broncos

Denver Broncos coach John Fox has seen enough to name Kyle Orton his starting quarterback.

What he hasn't determined is who's No. 2.

Fox said Tim Tebow and Brady Quinn have two more preseason games to win the job as Orton's primary backup.

Because the league's new rules don't mandate teams designate their quarterback rotation on game day any more, the winner of that QB competition might remain a mystery, however, barring an injury to Orton.

The Broncos began training camp trying to trade Orton but when no teams made an offer, they opened the competition and Orton quickly showed he was the best of the bunch.

He's gotten almost all the work with the starters.

"Well, we've talked to the quarterbacks, in particular Kyle," Fox said after practice Monday. "We're going to name him the starter for the opener against the Raiders (on Sept. 12). We've not really reached a conclusion on 2 or 3 yet, and won't, probably, until after the preseason games."

Orton's starting status hasn't really been in doubt since the first day of training camp, when he showed the gulf between him and the others was still enormous.

"He's played very well. He has great command of the offense, I think he has the most experience in this offense, and I think that's been evident," Fox said.

Tebow, who started the final three games last season and thought he'd be coming into camp as the incumbent, might slip to the No. 3 job as he continues to struggle with accuracy and mechanics while Quinn shows vast improvement from last year, when former coach Josh McDaniels didn't play him at all during the regular season.

During practice Monday, Orton spent a good deal of time tutoring Tebow on what looked to be mechanics and motion.

NFL's 49ers to ban tailgating after game starts — After a shooting marred a weekend preseason game against the archrival Oakland Raiders, the San Francisco 49ers moved to strengthen security at home games, including banning tailgating after kickoff and warning fans that rowdy behavior won't be tolerated.

In addition, 49ers CEO Jed York said he will recommend that the NFL call off the annual preseason battle between the Niners and Raiders indefinitely.

"This is a game where you have a rivalry situation and, unfortunately you have the worst segment from a very small segment of both fan bases that come and brings about this type of event," York said at a news conference at Candlestick Park. "It's our belief that we should recommend to the NFL that this game is at least postponed for some period of time."

Giants 41, Bears 13 — Brandon Jacobs scored on an 18-yard run, Domenik Hixon caught a 5-yard touchdown pass and the New York Giants cashed in on big special teams plays in a preseason victory over the Chicago Bears that was marred by the loss of starting cornerback Terrell Thomas to a major knee injury.

Thomas, the Giants leading tackler last season, torn the anterior cruciate ligament in his right knee with 22 seconds left in the first half in a collision with defensive end Jason Pierre-Paul.
