Although defensive tackle Peria Jerry got some work, coach Mike Smith already has ruled him out for the preseason opener against Kansas City. Cornerback Brian Williams and receiver Harry Douglas, who also are coming back from knee injuries, also have been ruled out. Smith said he’s optimistic all three can play later in the preseason.

Douglas didn’t take part Tuesday morning and starting receiver Michael Jenkins is out for four to six weeks with a shoulder injury. That paved the way for veteran receiver Brian Finneran to get a lot of work with the first team. This is situation obviously in flux with Douglas expected to keep getting more work as the preseason goes on. Rookie Kerry Meier also is getting lots of work and has responded well. But Finneran’s experience allows the first-team offense to get work done without a lot of disruption. He knows the system and, as a run blocker, is a reasonable facsimile of Jenkins.
