It seems as though Denver Broncos' wide receiver Javon Walker will be unable to come back from the knee injury he suffered during last week's loss against Jacksonville to play Sunday at Indianapolis. The injury prevented Walker from practicing most of this week and now looks as if it will prevent him from playing as well. Walker, who recorded 100-yard games in the first two weeks of the season, leads the Broncos in receptions (19) and is second in yards (230). He was held to two receptions for 10 yards in last week's loss to Jacksonville.
