The Dolphins made their acquisition of cornerback Chris Culliver official on Wednesday morning and they also announced the departure of two veterans from the roster.

Linebacker Danny Lansanah was released a week after joining the team in a move that appeared to be designed to increase the team’s defensive and special teams depth. The change of course suggests Lansanah wasn’t the fit that Miami was anticipating, but his experience — 22 starts for the Bucs over the last two seasons — could get him a look elsewhere before the summer is out.

The Dolphins also released offensive lineman Jacques McClendon. McClendon, who plays center and guard, was on and off the Dolphins active roster last year and played in three games before re-signing with the team in March. He’s also spent time with the Jaguars, Lions, Steelers, Falcons and Colts.

The moves leave an opening on Miami’s 90-man roster ahead of Friday’s first preseason game.
