Kyle Rudolph has been diagnosed with a broken foot, and could be sidelined "as much as a month." The "as much as a month" comes from coach Leslie Frazier, who also said the Vikings aren't sure of Rudolph's exact timetable. With the Vikings' season in the tank, it's quite possible Rudolph will eventually end up on injured reserve. It leaves John Carlson as the starting tight end. Considering how inconsistent the far-more talented Rudolph has been in the Vikings' scattershot offense, Carlson will likely struggle for TE2 value.
