Vikings linebacker Erin Henderson and wide receiver Michael Jenkins are both listed as questionable for Sunday's home game against the Tennessee Titans. Henderson, who has been out of action since suffering a concussion in a Week 2 loss to Indianapolis, practiced all week symptom free. Jenkins is nursing a rib injury that he sustained in last week's 20-13 win at Detroit, but also practiced fully on Friday after being limited in Thursday's session. Minnesota safeties Mistral Raymond (ankle) and Andrew Sendejo (ankle) have been ruled out, linebacker Marvin Mitchell (calf) is questionable, and quarterback Christian Ponder (knee), defensive end Jared Allen (groin), guard Charlie Johnson (back) and cornerbacks Marcus Sherels (quadricep) and Antoine Winfield (knee) are all listed as probable.
