Chad Pennington has been initially diagnosed with a torn capsule in his throwing shoulder and the Dolphins expect him to miss the rest of the season, sources familiar with the injury told ESPN's Chris Mortensen. Pennington will seek a second opinion from orthopedic specialist Dr. James Andrews, who has performed two shoulder surgeries on the quarterback. Pennington has already had surgery on the same shoulder in 2004 and 2005. Chad Henne, who went 10 for 19 for 92 yards with an interception, will likely make his first NFL start Sunday when the winless Dolphins play host to Buffalo. "We're going to have to go out there with Henne, who is a lot less experienced," tight end Anthony Fasano said. "There is definitely going to be a learning curve for Henne. He can learn as much as he wants in a classroom, but until he's out on the field, in-game experience he's not going to learn. "But we have a lot of faith in Chad. He's a smart guy, a great leader and fun to play with. We're just going to have to move on."
