Brown practiced in San Diego on Wednesday for the first time since rejoining the team he called home in 2012 an 2013 and is busy trying to reacquaint himself with the playbook and system, the San Diego Union-Tribune reports. Brown is back in San Diego after getting cut by Houston earlier in the week. A rash of injuries to all three of the top Chargers running backs has the Bolts scrambling for able bodies, and Brown became available at exactly the right time for them. While some things have changed in the playbook since Brown was last a Bolt, he is certainly more familiar with the schemes and plays than any other back would be, and could immediately see action. With Donald Brown looking like he might miss this Sunday's game, Branden Oliver will get the bulk of the touches, but Brown and also Shaun Draughn will be in the mix in reserve roles.
