Dangerous Play?

[wardtc]

Help me sort this out please.

Blue attacker is dribbling toward the Green team's goal. The blue attacker is not yet in an obvius scoring position. Green defender approaches from the wing and attempts a slide tackle. The green defender misses the ball, slides in front of the attacker. The ball continues in the direction the attacker was heading, and the attacker must jump over the defender in order to avoid contact. The attacker clears the defender (no contact is made), regains control of the ball, and continues toward the goal.

Is the proper call a dangerous play with the advantage clause applied? If so should the defender be warned as soon as is practical?

If the blue attacker looses the ball, should it be a dangerous play call right then?

Thanks for your help.
