Knowshon Moreno isn't the only Broncos RB who returned to practice Monday after tearing his right ACL last year. Mario Fannin, an undrafted rookie last year, also came back to practice after tearing his ACL in training camp. Fannin and Moreno wore bulky braces on their right knees during the 90-minute session. With Willis McGahee returning and Ronnie Hillman drafted in the third round, Fannin and Moreno appear to be part of a crowd fighting to be the No. 3 RB.
