Ravens rookie wide receiver Michael Campanaro has been scratched for his fourth consecutive game Sunday because of a pulled hamstring.
Campanaro (River Hill) returned to practice on a limited basis this week, but he won't return until next Sunday's game against the Miami Dolphins at the earliest.
This is the second hamstring injury that Campanaro has sustained since the Ravens drafted him in the seventh round out of Wake Forest in May. He pulled his hamstring during their rookie minicamp and was sidelined for most of the spring.
Campanaro then pulled his hamstring Oct. 26 during a loss to the Cincinnati Bengals after he caught three passes for 40 yards in the game.
On Sunday against the San Diego Chargers at M&T Bank Stadium, the Ravens also deactivated cornerback Rashaan Melvin, linebacker Arthur Brown, nose tackle Terrence Cody, guard Jah Reid, defensive end DeAngelo Tyson and center-guard Gino Gradkowski.
This marked the second consecutive healthy scratch for Brown, who was active against the Pittsburgh Steelers and Tennessee Titans. Reid participated fully this week after returning from a broken right hand that required surgery.
The San Diego Chargers scratched wide receiver Dontrelle Inman, running back Ronnie Brown, linebacker Andrew Gachkar, defensive tackle Damion Square, guard Ryan Miller, nose tackle Ryan Carrethers and outside linebacker Cordarro Law.
The Chargers signed rookie offensive lineman Jeremiah Sirles to their active roster from their practice squad Saturday and cut safety Adrian Phillips.
