No, for the player to get credit for a sack he would have to tackle the quarterback behind the line of scrimmage. The quarterback would have to be declared down for it to be counted as a sack.

When a defensive player tackles a quarterback behind the line of scrimmage as he is trying to throw the football .... that is called a sack.
No, it is not considered a tackle. Technically when a quarterback goes down behind the line of scrimmage it is considered a sack. However, when a quarterback takes a knee, he is credited with a -1 yard rushing but no defender is credited with the tackle/sack.
