Can Jogging And Riding Cause Any Problem After Injury?

Think I pulled hamstring week and half ago stretching to make shoelace catch in softball, wondering how long before I can play again, tried to kept playing after first injury and felt like it might have tore a little. Had acl recon in 2007 using hamstring graft, this injury is above knee inside hamstring,had some small bruising, can still jog and ride bike,just no sprinting without strain
