One day after making the initial 53-man roster, running back Aaron Brown was waived by the Lions. His agent, Jordan Woy, announced the move on his Twitter account, saying the Lions had released Brown to add another player they claimed off waivers. Brown, who had a strong training camp, amassed 189 yards on 44 carries in his two seasons with the Lions. His only touchdown came on a pass reception in 2009. The Lions have added three players to the practice squad thus far - receiver Nate Hughes and safety Ricardo Silva, both cut by the Lions on Saturday, and offensive tackle Casey Bender (6-5, 295, South Dakota State), who was cut by the Browns.

I don't think they have claimed anyone yet, they have 4 backs on the roster so far if they are counting Logan as a back...
