The Vikings may be down to two tight ends Sunday against the Bengals. Starter Kyle Rudolph was unable to practice Friday, marking his third missed practice this week due to an ankle injury suffered in Carolina. Earlier today, tight end Blake Bell was placed on injured reserve with a shoulder injury. Tight ends David Morgan and Kyle Carter, promoted from the practice squad on Friday morning, were the only two at practice again on Friday. Left tackle Riley Reiff donned a helmet again and rejoined the offensive line in position drills on Friday, however backup Rashod Hill also took snaps alongside left guard Nick Easton.
