Rudolph injured his groin in the Vikings' 20-9 loss to the New Orleans Saints on Sunday afternoon. He was listed on the Vikings injury report last week as a limited participant in practice due to an abdominal injury.
Prior to leaving the game in the fourth quarter, Rudolph caught three passes for 27 yards.
Rudolph missed the final eight games of last season with a broken foot.
In July, the Vikings signed the tight end to a five-year contract extension worth up to $40 million.
