Evening AFC West notes

Key Kansas City Chiefs reserve cornerback Javier Arenas was limited Friday by an ankle injury that did not keep him out of any work earlier in the week. Arenas, a top return man, is questionable to play Sunday against the visiting Miami Dolphins.

Chiefs safety Jon McGraw missed the entire practice week with a shoulder injury and he is doubtful to play Sunday. He was hurt Monday playing against the San Diego Chargers. Meanwhile, McGraw was named the team’s recipient of the Ed Block Courage award. Every NFL team honors one player each season.
