The Titans are putting starting right guard Leroy Harris on injured reserve with a partially torn anterior cruciate ligament in his right knee.
Harris hurt his knee on the opening drive in a 19-13 overtime loss to Indianapolis on Oct. 28 and had to wait for swelling to ease for a final diagnosis.
The Titans also announced other roster moves Wednesday, including signing defensive end Jarius Wynn and guard Kyle Devan. The 6-foot-3, 285-pound Wynn played 36 games for Green Bay and had 4 1/2 sacks after being drafted by the Packers in 2009. The Titans are bringing back DeVan, who was signed and waived last week by Tennessee.
Linebacker Rico Council was signed to the practice squad.
