The Eagles signed Mims to a contract Monday.
Mims will join the Eagles for the final week of training camp after being waived by the Vikings on Aug. 12. He's unlikely to make the 53-man roster by the end of training camp, but a strong week of practice and a nice performance in Friday's preseason finale against the Bengals could be enough to convince the Eagles' coaching staff to keep Mims around on the practice squad.
