I ran a search on the games in GM Robert Huebner's World Champion Fischer CD looking for a game where one side promoted a pawn to a rook. Chessbase reports 'no games found.' There were 47 games where someone promoted to a queen, but no games where someone promoted to a bishop or knight. This CD has close to 1000 of Fischer's games.

In the 8th game of Mikhail Tal's match with Bent Larsen at Eersel in 1969, Tal as White checked Black's king, sending it to d8. Later in the game he could have won by advancing his e-pawn, but became worried that Black could develop an attack by castling(!), and so focused his play on preventing this from happening. After the game, a fan asked Tal why he hadn't pushed the a-pawn, and it was only then that Tal realized his mistake. You can't castle once your king or rook have moved.
