It's finally coming to an end.

The Miami Dolphins visit the Dallas Cowboys at Cowboys Stadium on Wednesday to close the preseason.

Here's a preview.

Stephen McGee vs. Rudy Carpenter: The Cowboys are thinking about going with two quarterbacks. Tony Romo and Kyle Orton have guaranteed roster spots. After that, McGee, the third quarterback since 2009, and Carpenter, who is trying to make the active roster, will get a shot Wednesday night. McGee has been inconsistent this summer in camp practices and in three preseason games. Carpenter has led the third unit on a touchdown drive. McGee is the better talent, but roster issues could force the Cowboys to go with just two quarterbacks, unless someone emerges.

Claiborne and Spears should play: First-round pick Morris Claiborne and veteran defensive end Marcus Spears should play a little on Wednesday. Here's why. Claiborne, who missed the first preseason game with a knee sprain, needs to get more snaps before getting ready for the New York Giants on opening night. Spears is getting snaps with the second team and will most likely get a few snaps just to either keep him sharp or see if the Cowboys still want him on the team.

What's uncertain?: The third quarterback for one thing. And in reality, it doesn't matter who the No. 3 receiver is. Kevin Ogletree, Dwayne Harris and Cole Beasley will make the team, but who gets the sixth receiver spot is the question. Andre Holmes? Danny Coale? Tim Benford? The swing tackle is Jermey Parnell, but who out of Pat McQuistan, Daniel Loper, Derrick Dockery and Ronald Leary make the team? Orie Lemon, Shaun Chapas, Jamize Olawale, Adrian Hamilton, Lance Dunbar and Akwasi Owusu-Ansah are competing for a some of the final three or four roster spots.

The series with the Dolphins: The Cowboys lead the preseason series 4-2 and lost the last meeting 17-3 in South Florida. In that game, Sept. 1, 2011, receiver Raymond Radway fractured his leg on a pass in the end zone at the end of the game. Radway missed the regular season. He was cut this week by the Cowboys.

Connections: Dolphins general manager Jeff Ireland was a former executive with the Cowboys, and Brian Gaine, the Dolphins' assistant general manager, worked in the personnel department with the Cowboys. At one point the Dolphins had many former Cowboys. Now, there are only a few. Linebacker Kevin Burnett, for one, plays for the Fins.

Parking, parking, parking: For the second consecutive time, the Cowboys and Texas Rangers are playing at nearly the same time. Rangers first pitch is around 6:05 p.m. CT. Kickoff is scheduled for around 7:30 p.m. CT. Cowboys Stadium parking lots open at 2:30 p.m. East Plaza is open at 3:30 p.m. and stadium gates to all plazas open at 5:30 p.m. Fans who have pre-purchased parking in the Ranger Lots A-B and M will have their passes honored. Stadium officials ask fans to get their early due to the Rangers game.

By the way: Regular season starters like Tony Romo, DeMarco Murray, Brandon Carr and Sean Lee won't play. Just telling you.
