According to Tania Ganguli of the Florida Times-Union, Jacksonville Jaguars safety Dwight Lowery was taking first team reps at one of the safety positions in place of Courtney Greene. Lowery was acquired via trade from the New York Jets on cut day for an undisclosed conditional draft pick. Lowery is a utility defensive back, having experience at cornerback and both safety positions.
It's no surprise that Lowery has worked his way into the starting line-up, as I believe that was the plan all along when he was picked up. Greene is an adequate traditional strong safety, but he struggles in coverage. The NFL is moving towards a more pass heavy league and that fits Dwight Lowery better. Also, take into consideration the match up. The Jaguars are facing a team who's quarterback who has thrown for 400+ yards in each of his first two starts. One would expect the Carolina Panthers to continue to come out throwing the football.
