Denver Broncos quarterback Kyle Orton missed a third consecutive practice Friday with a sprained left ankle. Coach Josh McDaniels said Orton's availability for Sunday's pivotal contest with San Diego will come down to a game-time decision. Backup Chris Simms again took first-team practice repetitions, as he has all week in the absence of Orton, who was injured during last week's 27-17 loss at Washington. Source: National Football Post
