EDEN PRAIRIE, Minn. -- Minnesota Vikings coach Mike Zimmer said Tuesday that defensive tackle Linval Joseph will need surgery on the toe injury that bothered him for the final seven weeks of the season and that defensive end Everson Griffen, who dealt with a nagging shoulder injury at the end of the season, could need "something done" if he doesn't go to the Pro Bowl.

Wide receiver Adam Thielen will also need an operation on his shoulder, Zimmer said, and tight end Rhett Ellison already had surgery on the patellar tendon he tore against the Green Bay Packers Jan. 3.

Other than that, Zimmer said, the Vikings shouldn't have too many offseason operations. Running back Adrian Peterson said Monday he won't need any offseason procedures, like he had after 2012 and 2013, adding "the body feels good" after a league-high 327 carries this season.

The Vikings' 59-year-old coach, though, might not be quite as lucky.

"I have to get a knee operated on," Zimmer said, in response to a question about offseason surgeries, before laughing and saying, "Weren't you talking about me?"

What caused the need for a knee operation? "I don't know -- old age, stress," he said.
