Perriman, the team's 2015 first-round pick, hasn't practiced since suffering a significant hamstring injury on Aug. 1. He isn't expected to play in Thursday's preseason finale, which means he has only played in one preseason game in three NFL seasons. The hope is for Perriman to be Baltimore's No. 3 receiver behind Jeremy Maclin and Mike Wallace. In Perriman's absence, Michael Campanaro has been the third receiver.
