With the injury to Nate Allen and the release of Joique Bell, it was only a matter of time before the Eagles added a safety. According to a report out of KPAX in Montana, the Eagles have signed Colt Anderson off the Vikings practice squad. Anderson, who went undrafted in 2009, has spent the last two seasons with the Vikings and has never played a snap in the NFL.Given that Anderson likely has no knowledge of the Eagles offense, I would expect him to play exclusively on special teams for the Birds until Nate Allen is healthy. With Kurt Coleman and Quintin Mikell set to start at the two safety spots, Anderson will only see time in an emergency situation.
