New Jaguars strong safety Barry Church’s activity during the just-completed 10 organized team activity workouts has been limited training on a separate field, usually with free safety Tashaun Gipson. Church sustained a back injury in the early stages of the Jaguars’ off-season program and the team is obviously being cautious instead of crazy. Not having Church available for OTAs or next week’s mini-camp should not be a concern for the Jaguars – he is a veteran who knows how to play and the goal is to have him on the field Sept. 10 at Houston, not for a June 7 unpadded practice. “He’s a veteran, he’s a professional and as soon as he steps on the field, he’s going to communicate clearly,” strong-side linebacker Paul Posluszny said. “He knows exactly what to do.” Church has played 90 games (63 starts). From 2013-16, Church played 89.1, 86.7, 81.6 and 63.9 percent of the Cowboys’ defense snaps. But he has a to-be-monitored medical chart: Shoulder in December 2011, torn Achilles in September 2012, broken arm in December 2015 and broken forearm last October. The Jaguars shifted their safety plan in March when they signed Church away from the Cowboys to replace Johnathan Cyprien, who signed with Tennessee.
