It would depend on the relative position/closness of the striker and the CB, and if the striker was deemed interferring with the CB, hence the need to put it out of play. Difficult to judge this from the original description.
Here's the relevant part of the law:
interfering with an opponent by:
- preventing an opponent from playing or being able to play the ball by clearly obstructing the opponent’s line of vision or
- challenging an opponent for the ball or
- clearly attempting to play a ball which is close to him when this action impacts on an opponent or
- making an obvious action which clearly impacts on the ability of an opponent to play the ball
