The Lions' final injury report before Sunday's game against the Titans was released on Friday afternoon and features tight end Tony Scheffler listed as doubtful. After suffering concussion symptoms that almost caused him to miss Week 2, a calf injury withheld Scheffler from practice all week and will likely keep him from seeing the field against the Titans.
Also doubtful are safety Louis Delmas with a knee injury and linebacker Travis Lewis with a quad injury. Hopeful to play is defensive tackle Corey Williams who missed both Wednesday and Thursday practices before coming back on Friday to limited reps. He is listed as questionable as is cornerback Jacob Lacey who didn't appear on the injury report until a toe injury caused him to be limited on Friday.
Chris Houston is set to make his 2012 debut with a probable listing. Also probable are Bill Bentley and Calvin Johnson.
