The Minnesota Vikings placed center John Sullivan on short-term injured reserve Thursday due to a back injury. He is eligible to practice after six weeks and can play in game after eight weeks.
The team also announced Sullivan underwent a lumbar microdiscectomy Wednesday.
"As a player you never want to miss time," Sullivan said. "Regardless of the circumstances surrounding your absence, you feel guilty about not fulfilling your responsibility to your teammates, coaches, organization and fans by giving it your absolute best out on the field every Sunday.
"While I'm incredibly disappointed that I'll be missing the first portion of the 2015 season, I have full faith in the roster that our coaches and front office have put together. Joe Berger will step in and do a great job leading our offensive line, protecting the best young quarterback in football and opening up holes in the running game.
"In the meantime, I promise I'll be doing everything I can to recover and I'll be ready as soon as humanly possible to return to the field and help the Vikings win their first Super Bowl Championship."
The status of Minnesota Vikings running back Adrian Peterson is up in the air, and while the veteran may not have interest in returning to Minnesota, center John Sullivan made it clear Thursday's night in an interview on Sirius XM NFL Radio Thursday night that the Minnesota players want Peterson back, Pro Football Talk reports.
"We want him back. There is no doubt the players want him back," Sullivan said. "He missed an entire season. He more than paid his dues with this whole thing. I respect him as a man. I don’t want to talk too much about it just because I don’t want to put too much conjecture out there but I just hope it works itself out and he comes back and joins us. We have open arms here waiting for him. We want to rush for the 2,500 yards that he talked about a couple of years ago."
The league reportedly filed an appeal in the Peterson case Wednesday to preserve the disciplinary powers of commissioner Roger Goodell. Peterson met with Goodell Tuesday, but an official decision on his reinstatement has yet to be announced.
The Minnesota Vikings announced Tuesday they extended center John Sullivan 's contract by one year through the 2017 season.
"I want to start by saying thank you to the Minnesota Vikings for putting their faith in me as a person and football player," Sullivan said. "The Vikings have been with me through professional highs and lows, and have stood by my side and supported me through personal hardships. My ability to express the true depth of my gratitude comes from my actions on and off the field."
The Minnesota Vikings extended center John Sullivan 's contract by one year through the 2017 season, a source told ESPN.

The Minnesota Vikings have placed 11 players on their Friday injury report, but only two have been deemed worse than questionable. They are ruled-out tight end Kyle Rudolph (abdomen/groin) and doubtful linebacker Gerald Hodges (hamstring).
