Jaguars safety Courtney Greene injured his left shoulder in the first quarter of Sunday's 17-6 win over the Tennessee Titans. Greene suffered the injury on the fifth play of the game after tackling Titans running back Chris Johnson. Johnson gained two yards on the carry. "Don't know what's wrong with it, find out tomorrow," Greene said. "It's moving all right actually." Greene underwent X-rays at LP Field and said they did not show any fractures. He will have an MRI today. Greene has been the Jaguars' starting strong safety since their Oct. 18 game against Tennessee in Jacksonville.
