Sanders, the 2007 NFL Defensive Player of the Year with Indianapolis, was placed on the season-ending injured reserve list today because of a knee injury he suffered in the second game of the season. He signed with the Chargers in the offseason and, before this injury, had missed the equivalent of four seasons since entering the NFL in 2004.

“From the standpoint of where his knee is, it was a decision that was the right one,” Coach Norv Turner said. “When you make a decision like this, it's based on medical facts first and included our feelings and his. I know that it was going to be difficult for him to continue. I've had a number of conversations with Bob over the last few days. This is difficult for him. I'm very respectful of what he tried to do for us and I wish his impact would've lasted longer.

“It's not something anyone could've anticipated. It's something that just happens.”
