Turzilli is dealing with both a groin and thumb injury, Terry McCormick of TitanInsider.com reports.
It's unclear exactly when he suffered the injuries, but it's likely going to keep him limited for the time being. The Titans face off with the Panthers on Saturday in the team's second preseason outing, so it remains questionable whether or not Turzilli will be available. Turzilli is suspended for the first four games of the season for his use of performance-enhancing substances, making the injury just another hit to his chances of making the final roster.
