Wrapping up the preseason

A look at some key aspects of the preseason finales for the AFC West:

•Denver right tackle Ryan Harris suffered an ankle injury in Denver’s 31-24 loss at Minnesota. It is not known how severe the injury is. It is another reminder that starters shouldn’t be playing in the final preseason game.

•Two Denver receivers performed well. Third-round pick Eric Decker had 10 catches for 114 yards. Now that he is healthy, Decker could be an immediate factor. Matthew Willis might have solidified his spot on the 53-man roster with five catches for 122 yards. Willis’ big night might mean veteran Brandon Stokley’s job could be in jeopardy.

The Chiefs beat Green Bay 17-13, registering their first preseason win since 2008, Rookie Javier Arenas had a 44-yard kickoff return. Arenas had several big returns in the preseason, and he looks like he has a chance to be a dynamic return man. The Chiefs continued their terrific preseason on the ground as backup Jackie Battle showed his explosion with a 50-yard run.

In Oakland, Bruce Gradkowski continued to move the chains. He threw for 128 yards and he had two touchdowns passes in the Raiders’ 27-2 win against Seattle. Once again, Gradkowski showed he can be effective if starter Jason Campbell can’t play at some point. Trevor Scott played defensive end. He had been penciled in as a starter at linebacker after moving from defensive end last season. Oakland coach Tom Cable was vague after the game about where Scott will play.

In San Diego’s 17-14 loss at San Francisco, receiver Buster Davis looked good. The 2007 first-round pick had four catches for 82 yards and looked spectacular doing it. If he can stay healthy, Davis has a chance to be a productive No. 3 receiver for San Diego.
