Cowboys' remaining RT options

Stretching back to the start of the offseason for the Dallas Cowboys, there has been a lot of discussion as to what exactly the team plans to do with Doug Free. At one point, the Cowboys felt strongly enough about the Northern Illinois product to sign him to a four-year, $32 million deal. In the time since, he's been shifted from LT to RT, and from starting RT to part of a platoon at the position with Jermey Parnell. While there has been talk that he'd simply be released if he didn't agree to a pay cut, the Cowboys have been losing replacement options left and right over the past few weeks, the latest of which was Tyson Clabo, who agreed to a deal with Miami on Sunday. So who's left?
