That's because he underwent hip surgery that will keep him out at least for the next three months, according to CBS Sports' Jason La Canfora. The surgery, according to Fox Sports' Mike Garafolo, was for a labrum repair. ESPN's Adam Schefter was the first to report the news.

If he's out for three months, Pouncey would miss all of training camp and the first few weeks of the season before he could return.

Which also means that the Dolphins will have an entirely different Week 1 starting lineup on the offensive line than they did last year with the loss of Pouncey, the PR disaster that was left guard Richie Incognito, and the trade of left tackle Jonathan Martin. Right tackle Tyson Clabo is now a free agent, while right guard John Jerry now plays for the Giants.

For now, Sam Brenner is listed as the Dolphins backup center, so it makes sense that he could be the one to move into Pouncey's spot.

According to the Pro Football Focus metrics, Pouncey was rated as the league's 13th-best center last season.
