Rob Turner's season is over for the Tennessee Titans.
The center, who started the first six games of the season before being replaced by rookie Brian Schwenkie just before the bye, was placed on injured reserve with a shoulder injury.
To replace Turner on the 53-man roster, the Titans signed offensive lineman Pat McQuistan, who had been in camp with the club in 2011 but did not make the 53-man roster.
Also, the Titans made moves on the practice squad. They lost defensive tackle Stefan Charles, who was signed by the Buffalo Bills to their 53-man roster. They replaced him with defensive lineman Chigbo Anunoby. They also signed back guard Oscar Johnson to the practice squad and waived practice squad receiver Rashad Ross.
Turner had signed a one-year deal in the off-season with the Titans after being with the St. Louis Rams last year.
