EDEN PRAIRIE, Minn. - Vikings running back Adrian Peterson will have surgery on his damaged right knee Thursday, and could miss the remainder of the 2016-2017 season.
ESPN Reporter Josina Anderson posted on Twitter that the second opinion on Peterson's knee revealed what is known as a "bucket handle tear," an injury with a minimum recovery time of three to four months, and sometimes up to six months.
Peterson has what is known as "bucket handle tear." I'm told that's a minm of 3-4 months out & up 6months usually. Again Peterson has faith.— Josina Anderson (@JosinaAnderson) September 21, 2016
Zimmer confirmed that Peterson will undergo surgery Thursday but said the timeline for returning would not be determined until a surgeon can assess the extent of the damage.
"Everything is possible," Zimmer said. "Could be season-ending, could be three weeks, four weeks. Who knows?"
Zimmer announced that Jerick McKinnon will start Sunday against Carolina. Ronnie Hillman, most recently of the Denver Broncos, was signed to provide depth at the running back position in Peterson's absence.
Zimmer also told reporters that left offensive tackle Matt Kalil was placed on the Injured Reserve list with a hip injury, adding they assume his season is over.
T.J. Clemmings will move over from the right side to replace him.
"We’re not the type of team that’s going to sit back and cry," Zimmer said of the injuries.
