Why is my "yield" statement stopping my script?

Hi, I can't seem to figure out what is wrong with my script. I am creating a roller ball game and I want the ball to disappear when it triggers a hit on the wall. Everything works great separately but when I add a line to get rid of the camera follow script, the script stops at my "yield" command. If I remark out the "yield" command, it works fine but there isn't enough time to complete the explosion and sound before it loads the "reset" level. Can someone please take a look at my script and tell me why it stops at "yield"? Thank you so much!!! Tom

 #pragma strict
 
 var explosionEnd : Transform;
 
 function Start ()
 {
 
 }
 
 function Update ()
 {
 
 }
 
 
 function OnTriggerEnter (myTrigger : Collider)
 {
     if(myTrigger.gameObject.name == "WallSide")
     {
         
         //Create explosion wherer the ball is (not done yet)
         Instantiate (explosionEnd);
         
         Debug.Log ("I hit something.");
         
         //Make the RollerBall disapear
         Destroy (gameObject.Find("Player"));
         
         //Get rid of the camera script so it stops trying to find the RollerBall
         Component.Destroy(Camera.main.gameObject.GetComponent("CameraFollow"));
         
         Debug.Log ("This is the second message.");
 
         //Wait for the explosion and sound to complete
         yield WaitForSeconds(2);
         
         //Load the start over menu level
         Application.LoadLevel ("Level 7 Reset");
         
         Debug.Log ("This is a third message.");
     }
