NT Mike Purcell likely practice squad promotion

With defensive end Ray McDonald “terminated” by the San Francisco 49ers on Wednesday in light of him being investigated for sexual assault, the team currently only has four defensive linemen currently on the 53-man roster in Justin Smith, Tony Jerod-Eddie, Quinton Dial and Tank Carradine.

49ers coach Jim Harbaugh was asked Thursday who could be promoted from the team’s practice squad to provide depth for Saturday’s game against the San Diego Chargers.

“Mike Purcell would the next option,” Harbaugh said.

“He’s been good. He’ll do a good job.”

With Dial the lone nose tackle, the 6-feet-3, 303-pound Purcell has a leg up on fellow D-line practice squad player Lawrence Okoye, who is primarily an end in the Niners’ 3-4 base defense.

“He’s ready to go,” Harbaugh said of Purcell, “and (we) feel very confident that he’ll do a good job.”

Jerod-Eddie figures to start in place of McDonald, alongside Smith at the other end and Dial at nose.
