Knowshon Moreno will undergo knee surgery and will miss four to five weeks.

Moreno is competing for carries in the Miami Dolphins' backfield.

Mike Pouncey underwent hip surgery on Monday and is expected to miss at least three months.

The Miami Dolphins will begin the season with an entirely new offensive line.

Pouncey was a Pro Bowl selection in 2013.

Dan Marino will withdraw from the concussion lawsuit that lists him as one of the new plaintiffs.

“It was never Marino’s intention to initiate litigation in this case, but to ensure that in the event he had adverse health consequences down the road, he would be covered with health benefits. They are working to correct the error,” an unnamed source told the South Florida Sun-Sentinel.

Lawyer Sol Weiss will now face questions about how Marino’s name landed on a lawsuit if that wasn’t his wish.  It’s possible Marino signed something that he didn’t realize would result in a suit being filed.

Marino is attempting to secure a job with the front office of the Miami Dolphins.
