Chargers sign Ryan Miller, cut Richard Crawford

SAN DIEGO -- A signal that center Rich Ohrnberger will not be active on Sunday against the St. Louis Rams, the San Diego Chargers signed offensive lineman Ryan Miller from the practice squad to the active roster on Saturday.

To make room for Miller, the Chargers released cornerback Richard Crawford. A University of Colorado product, Miller was added to San Diego’s practice squad on Nov. 11 after a workout during the team’s bye week.

Miller was drafted in the fifth round by the Cleveland Browns in the 2012 draft. He appeared in eight games for the Browns as a rookie. Miller went to training camp with the Denver Broncos, but was released during final roster cuts.

With Ohrnberger questionable for Sunday’s game against the Rams due to ankle and back issues, rookie Chris Watt is slated to get his first career start at center. Miller could serve as depth at interior offensive line, along with center Trevor Robinson, with Watt starting.

Crawford signed with San Diego on Oct. 27 after the team released cornerback Richard Marshall. But Crawford was not active on game day for the Chargers during his time with the team.
