"Tony Sparano said he had "no idea" who his starting quarterback would be Thursday night against the Bears, but it looks like his choices have been narrowed to one: Tyler Thigpen.

According to a team source, both Chad Pennington and Chad Henne are "more than likely" out for the season after suffering serious injuries in Sunday's 29-17 win over the Tennessee Titans.

A second team source said Pennington is "probably" out for the year with a fourth career injury to his throwing shoulder, but there is still "a lot left to learn" on Henne's injury to his left knee.

With the Dolphins needing to sign at least one and likely two quarterbacks this week, journeyman Patrick Ramsey, former Raider JaMarcus Russell and ex-Bronco Tom Brandstater have reportedly been contacted.

Ramsey, who hasn't started an NFL game in five years, has made four appearances since the 2006 season began. He spent the 2010 preseason with the Saints.

Henne left the locker room on crutches and had a 6:30 p.m. MRI scheduled on his left knee, which was twisted while throwing an incompletion late in the third quarter. Henne said his kneecap was hit from the outside and "bent forward" on the play.

"It doesn't feel good," Henne said. "For me, if I can stand and I can run around, I'm going to be playing. Obviously, I'm not going to be the one to baby my knee. If I can be out there, I'm going to be out there."

Pennington opened the game with his first start since Week 3 of 2009 but injured his thrice surgically repaired right shoulder on the first play of the game. He stayed in for one more play before leaving for good."
