Tight end Tony Scheffler (calf), Travis Lewis (quad) and Louis Delmas (knee) are all listed as doubtful for Sunday’s game at the Tennessee Titans on Friday’s injury report. None of them has practiced all week.

If Scheffler does not play expect tight end Will Heller and rookie wide receiver Ryan Broyles to see more action. Broyles was activated last week but did not play in the loss at San Francisco.

Cornerback Jacob Lacey made his first appearance on the injury list all week. He was limited in practice on Friday with a toe injury. He’s listed as questionable as is defensive tackle Corey Williams who has a knee injury.

Chris Houston (ankle), Bill Bentley (concussion) and Calvin Johnson (foot) are all listed as probable.
