Rudolph sustained the injury after scoring a touchdown and did not return to the game. According to Krammer, Vikings coach Leslie Frazier announced on Monday that Rudolph had fractured his foot and would be out for a month. Frazier would not call the injury season ending at this point.
Fantasy spin: Rudolph was an inconsistent fantasy football tight end before the injury because of his quarterback play, but this officially sinks his fantasy value for the time being. It's worth monitoring his progress in the coming weeks to see if Rudolph can be of use in the playoffs, but he's not worth rostering.
The Vikings' passing game has become a fantasy football wasteland. Rudolph was the last remaining player of value, and he can safely be dropped at this point.
