Minnesota Vikings coach Mike Zimmer said tight end Kyle Rudolph underwent groin surgery on Tuesday, according to Chris Tomasson of the St. Paul Pioneer Press.
Zimmer said he hopes Rudolph will be back before Week 8. It was reported Monday that he would miss about six weeks.
Rudolph left Sunday's loss to the New Orleans Saints in the fourth quarter after injuring his groin. In three games this season, he had 10 catches for 96 yards and one touchdown.
A broken foot ended Rudolph's 2013 season after eight games.
In July, Rudolph signed a five-year contract extension with the Vikings that could be worth up to $40 million.
