Smith was a non-participant in Wednesday's practice due to a back injury.
Smith missed two of the last three games due to a groin issue, but he now appears to be dealing with a new injury. Courtney Cronin of ESPN.com relays that while Smith was in attendance for Wednesday's workout, he wasn't sporting a helmet. Kyle Rudolph will operate as Minnesota's clear top tight end again if Smith can't return Week 13 against the Jaguars.
