During his time in Oakland, Grove also lined up at left guard and right guard.
Make no mistake, though, the Dolphins got him to play center, where the 6-4, 300-pound Grove will give Miami a more physical presence than it had last season with Samson Satele.
In his five seasons, Grove started 46 of the 54 games he played. He started 12 games last season and, ironically, one of the games he missed was Oakland's visit to Dolphin Stadium, a game the Dolphins won 17-15.
Grove became the second unrestricted free agent signed by the Dolphins this offseason, joining fellow guard/center Joe Berger, who came over from Dallas.
The Dolphins also signed safety Gibril Wilson, but that came after he was released by Oakland and technically isn't considered an unrestricted free agent signing.
