Interim coach Bruce Arians confirmed Vick Ballard is in for a heavy workload in Sunday's game against the Texans. With Delone Carter and Donald Brown sidelined by ankle injuries, Ballard will be backed up by street free agents Mewelde Moore and Deji Karim. "As long as he can stay in there he'll stay in there and when he needs to tap out, Mewelde will go in," Arians said. Ballard can safely expect to push for 20 touches, but the concern is that the Texans' defense eat up the Colts' depleted offensive line. They figure to come out focused and angry following Monday night's humiliation at the hands of the Patriots, leaving Ballard as a mere flex option.
