Miami Dolphins center Mike Pouncey underwent hip surgery Monday and is expected to miss the next three months, according to ESPN’s Adam Schefter.

NBCSports.com reported Pouncey tore a labrum in his hip and “it’s a significant tear.” NBCSports said that a three month recovery is a minimum and “it’s a very optimistic assessment.”

A three month recovery period would bring Pouncey back to the lineup around the third or fourth week of the regular season. The Dolphins could choose to place Pouncey on the Physically Unable to Perform List which would hold him out for six games.

Pouncey was the only holdover from last year’s offensive line and had started all 46 games that he’s played for the Dolphins. His contract was extended in the offseason through 2015.

With Pouncey out, the Dolphins will enter Week 1 against the New England Patriots with a completely new offensive line. The Dolphins offensive line without Pouncey would have the following starters: left tackle – Branden Albert; left guard – Dallas Thomas; center – unknown; right guard – Shelley Smith; right tackle – Ja’ Wuan James.

In the Dolphins’ most recent offseason work, Sam Brenner worked a lot at the center position.
