Former Dolphins starter Todd Pinkston, the six-year veteran who missed the entire 2005 season with a torn right Achilles, has been limited for much of training camp. Eagles officials have granted Pinkston and agent Joel Segal permission to speak with other teams about a potential trade. It is not certain what Philadelphia would be seeking in return for Pinkston, who could be extraneous, given the glut of receivers on the roster.
