"Knowshon Moreno's season is over.

Coach John Fox said today that Moreno will be placed on injured reserve after the running back tore his anterior cruciate ligament Sunday in Kansas City.

Moreno had rushed four times for 52 yards in the first quarter against the Chiefs, including runs of 24- and 22-yards before he was injured.

"I feel for him because he battled. He had that hamstring early in the season and battled back from that, and was getting back into the groove," Fox said. "He was having a really, really good day. It's unfortunate. But he's tough-minded, and will battle back from this.""
