Hey, kids, it's the year of starting centers going on the IR-Designated to Return list. You all knew about Maurkice Pouncey in Pittsburgh. Yesterday, New England put center Bryan Stork on IR-Designated due to a concussion. The expectation is that the Patriots will slide Ryan Wendell back to center and start two rookie guards, Tre Jackson and Shaq Mason, but Wendell may not be ready to go tonight. That would mean the Patriots start undrafted rookie David Andrews in the season opener. An even bigger surprise in Minnesota today, where John Sullivan had back surgery today. The Vikings may have a better backup plan, with veteran Joe Berger stepping in at center. Both Sullivan and Stork are now out at least through Week 8.
