Player's tee shot heading towards thick bushes
Player announces playing Provisional Ball it also goes straight towards same thick bushes.
Player unable to find either ball and decides to take 2 shot penalty drop on fairway at or near agreed area where 1st ball deemed lost - therefore playing 4th shot.
Question is - should player take 2 shot penalty by drop on fairway at or near agreed area where Provisional ball deemed lost (assume same large bush) - therefore playing 6th shot.
Club has adopted drop on fairway rule for lost ball.
Cannot find definitive rule to cover this.
Can anyone help? Thanks Brian.
