Broncos RB C.J. Anderson has right knee injury (The Associated Press)

C.J. Anderson might be going from breakout to heartbreak. The Denver Broncos were bracing for bad news on their starting running back, who they sent for a second opinion on his ailing right knee Wednesday. Anderson hurt it on an 11-yard run on the final play of the first quarter Monday night against Houston but returned to the game and ran 14 more times for 84 yards to spark Denver’s 27-9 win.
